1.1. GENERAL

Read this section and this manual before starting work on any part of the system.

When working on live equipment (batteries are always live), a second person who is aware of

all safety precautions and emergency actions should be present at all times.

It is the responsibility of each individual to be aware of national legislation, local legislation

and site rules governing safety and working practices. If in doubt ask.

Use only good quality insulated tools and accessories, properly maintained and calibrated

instruments, and suitable and adequate supports and lifting equipment.

It is essential that all safety instructions are strictly observed.

Note : A note in this style is used to emphasise an important point in the text

CAUTION : USED TO PREVENT DAMAGE TO EQUIPMENT.

WARNING A WARNING IS USED TO ALERT PERSONNEL TO

HAZARDS TO PERSONAL SAFETY.

Installation, maintenance and repair of the equipment and batteries should only be undertaken

by trained, experienced and authorised electrical personnel.

The handling, installation and maintenance of the battery associated with this equipment must

be in accordance with the instructions and safety precautions published by the battery

manufacturer.



CHLORIDE

INDUSTRIAL SYSTEMS

1.2. NATURE OF HAZARD

ELECTRICAL ENERGY can be supplied from the battery, the charging equipment, the AC

supply or the external alarm or auxiliary control terminals. The battery terminals are LIVE at

all times. A short circuit, even on a discharged battery, will result in a high current which can

cause personal injury, fire or damage to the battery or battery cables.

BATTERY ELECTROLYTE in ALL batteries is dangerous and can cause severe burns if

allowed to come into contact with the skin or eyes. It will also attack clothing and some paint

finishes and metals. LEAD ACID batteries contain sulphuric acid solution.

VENTED or FLOODED cells (Planté, Flat Plate and tubular lead acid or cells) contain free

liquid electrolyte which can spill if the cell is overturned, overfilled or the cell container is

broken.

HYDROGEN and OXYGEN are given off at the cell plates during charging and can be

present at other times, particularly if cells are moved or shaken. Hydrogen in conjunction with

air or oxygen can be explosive in the presence of sparks or flame.

In vented cells the hydrogen and oxygen are vented to the air.

Battery cells or cellblocks can be very heavy and often have to be moved to positions with

difficult access. When working on batteries with many cells or blocks, muscle strain may

occur suddenly or after battery installation is complete.

1.3. SAFETY PRECAUTIONS

Use only insulated tools, particularly when connecting a battery. Stand on a rubber mat.

Personal effects of metal such as rings, watches, bracelets and necklaces which may cause a

short circuit and metal objects (pens, tools etc) which may fall from open pockets while

bending over batteries or chargers should be removed.

Isolate all AC supplies, auxiliary supplies and the battery (open isolator, remove battery fuses

or remove a battery link) before working on the equipment. Never handle a component or

assembly without personally confirming that no voltage is applied or present.

If it is necessary to make adjustments with the equipment connected to the AC supply and/or

the battery, remove only those protective covers which are absolutely necessary for access.

Always use eye protection and rubber gloves when handling cells. Handle cells with care,

ensuring they are kept upright.

Use properly constructed staging or platforms as a resting-place close to the final position and

enlist assistance with large cells or large numbers of cells. Keep the back straight and upright

when lifting cells. Use only proper lifting techniques.

It is recommended that battery rooms should be provided with an eyewash bottle filled with a

fresh saline solution and a supply of clean water with means of directing on burns and

splashes. There should also be a safety shower in the battery room.

Do not smoke. Do not use open flames. Avoid creating an arc or sparks when working on thisequipment. Avoid wearing clothing which is susceptible to discharge of static electricity.



CHLORIDE

INDUSTRIAL SYSTEMS

Page 9 of 65

Always use pure distilled or de-ionised, de-mineralised water when topping up vented battery

cells. Do not use the same topping up apparatus or hydrometer for both nickel cadmium

alkaline and lead acid cells. Even small quantities of electrolyte transferred will damage or

destroy cells.

After work is complete, refit all protective covers and close and lock all doors.

1.4. EMERGENCY ACTION AND TREATMENT

ELECTRICAL SHOCK - Immediate action is essential. Severe electric shock may affect

heart action and breathing.

Make sure it is safe to approach. If the casualty is in contact with a live conductor, isolate by

switching off the supply. See section 5 "EMERGENCY SHUTDOWN". If this is not

possible, or it is doubtful whether the system is electrically isolated, stand on dry insulating

material and pull or push the casualty clear using dry insulating material, e.g. wood, plastic,

fabrics etc.If necessary give artificial respiration.

Seek the assistance of others to summon medical attention.

ELECTRICAL BURNS - Apply a dry sterile dressing.

ELECTROLYTE CONTACT - EYES - Irrigate the eyes with a saline solution. If saline

solution is not available wash with clean running water for at least 10 minutes

SKIN - Wash skin burns with plenty of clean water. Remove any contaminated clothing.

Cover the area with dry gauze.

IN ALL CASES SEEK IMMEDIATE MEDICAL ATTENTION.

ELECTROLYTE SPILLAGE - These should be washed away using large volumes of clean

water or mopped up using absorbent material which should then be sealed in secure

containers and sent to a recognised chemical disposal company.

Operatives handling spillage should wear adequate clothing including eye protectors andgloves. Electrolyte will attack many fabrics. In the event of spillage on clothing, the garments

should be removed and washed thoroughly in large volumes of clean water or discarded.

1.5. SAFETY - VENTED LEAD ACID BATTERIES

WARNING : IN CASES WHERE THE UNIT IS NOT BEING USED, E.G.

DURING MAINTENANCE, IT IS RECOMMENDED TO

DISCONNECT THE BATTERY TO AVOID IT DISCHARGING

AND BEING DAMAGED.

Nature of hazard.

The hazards are

Risk of electric shock

Risk of electric burns

Risk of chemical burns

Risk of poisoning

Risk of explosion from charging gases.

ELECTRIC SHOCK

An electric shock from d.c. is more damaging than a shock from a.c. of the same voltage

because d.c. has the characteristics "NO-LET-GO" due to the muscles being contracted by the

single direction of flow of the current. Risk of d.c. shock between battery terminals and earth

is limited in this equipment by incorporating double wound transformers in both the inverter

and rectifier so that the entire d.c. link is floating. Anyone coming into contact with it

accidentally will experience only the equalising charge which is unlikely to cause injury.

However, this protection could be defeated if, for example, a metal tool were to fall between a

battery terminal and earth (wooden battery stands are preferred for this reason).

The system would continue to perform normally but the battery and d.c. link would be in a

dangerous condition. Where an earth fault detector is fitted this will raise an alarm. The

principle of operation is to verify that the d.c. positive and negative rails are respectively at

symmetrically voltage with respect to earth. Any abnormal short, event of high resistance,

will disturb this symmetry.

WARNING: IF THE EARTH FAULT ALARM IS ACTIVE DO NOT CARRY

OUT MAINTENANCE ON THE BATTERY.

The other possibility for electric shock would be if a person were to come into contact with

two distant battery terminals in the same string. This possibility is avoided by arranging for

the battery layout to be configured so that the maximum distance separates the highest voltage

differences.

ELECTRIC BURNS

The prospective short circuit current from a battery is very big. So even a modest cell will

deliver over a thousand amps into a short circuit such as a metal watchstrap or an uninsulated

tool. The battery assembly may consist of well over a hundred cells in series in many

applications so the potential for serious injury exists.

WARNING: REMOVE METAL RINGS AND WATCHSTRAPS WHEN

WORKING WITH BATTERIES. USE PROPERLY

INSULATED TOOLS.

CHEMICAL BURNS FROM ELECTROLYTE

The electrolyte is sulphuric acid. It is corrosive to clothing and to living tissue. Even minute

traces can cause irritation and make holes in clothes.

When preparing electrolyte or topping up batteries wear full protective clothing.

Protect the eyes nose and mouth either with goggles and facemask or wear a full-face visor.

Protect the body with all enclosing overalls.

Protect the hands with gauntlets.

Protect the feet with boots that have sealed seams. Stitched seams can allow seepage.

An eyewash must be available and any splashes must be flooded with copious amounts of

water or saline solution to dilute the acid. Seek medical attention.

Neutralising agent must be on hand. Scatter it on any acid spills.

NOTE : Lead acid electrolyte is acidic, Nickel Cadmium electrolyte is alkaline so

different neutralising agents are needed.

POISONING

If electrolyte is swallowed it will be corrosive to internal organs.

Medical opinion is divided on whether to attempt to dilute it with milk or water or to do

nothing until medical help arrives.

Therefore at the outset consult the local medical authority who would have to deal with an

emergency and post suitable notices in the battery room.

Title Page

2.1. DESCRIPTION 14

2.2. TOPOLOGY 14

2.3. OPERATING MODES 17

2.1. DESCRIPTION

The Uninterruptible Power System (UPS) is designed to supply AC sinusoidal, electric power

that cannot be interrupted by abnormal occurrences on the public electricity supply. It is

designed on the "double conversion" principle whereby the public supply is used to power a

battery charger in order to store energy to be used during a power cut. This DC supply is then

inverted within the equipment to a pure quality sine wave which is immune to defects on the

incoming AC supply.

2.2. TOPOLOGY

The System consists of two UPS equipments connected in parallel to share the load. Each uniton its own is rated to support the full load. If either one fails then the surviving unit will

sustain the full load without break.

Each equipment consists of four major parts, see Figure 2.1. Block Diagram, the Rectifier/

Charger, the Battery, the Inverter and the Static Switch. The reserve is through a transformer.

Figure 2.2 : Voltage Current Characteristic of Charger

RECTIFIER/CHARGER

Converts the Primary AC supply to a regulated D.C. voltage which charges the battery,

powers the inverter and therefore the load. It operates in four possible modes.

Mode 1. FLOAT MODE. This is the normal mode. It is a constant-voltage charge mode so

battery charge current will tend to taper off to near zero as the battery becomes

fully charged. The voltage chosen is that value at which the internal losses arecompensated by the charge current into a charged battery. The battery is

maintained fully charged yet remains below gassing voltage so that the rate of

loss of electrolyte is negligible.

Mode 2. AC SUPPLY FAIL MODE. When the power to the charger is interrupted the

charger stops and without any switching taking place or operator intervention the

battery supplies the inverter and hence the load.

Mode 3. CHARGE MODE Automatically selected when the AC supply is restored.

Slightly higher constant voltage charge to shorten the time to recharge the

battery. It is controlled by two timers. Timer No.1 selects CHARGE MODE afteran AC supply fail has lasted more than a minimum specified time. Timer No. 2

terminates CHARGE MODE after a specified duration. It can be engaged or

terminated manually by an operator by means of push buttons inside the cubicle.

Mode 4. BOOST MODE Very high constant voltage charge. Intended for use at

commissioning to complete the forming process of the battery plates. It can only

be engaged manually, by an operator. It is terminated either manually or by an

inbuilt clock. For safety the battery charging current limit threshold reduced

during BOOST mode.

BATTERY

This stores energy from the charger to be used during a power cut when it will discharge to

power the inverter and load.

The autonomy of the system during a mains fail depends on the amp-hour capacity of the

installed battery.

INVERTER

Converts the d.c. power to sinusoidal a.c. power. Uses a high frequency pulse width

modulation (PWM) switching technique to achieve low distortion sinewave power while

retaining good transient response voltage regulation. Operates in the following modes.

Mode 1. NORMAL Constant voltage output regulated to ±1% for power loading between

0 and 105%.

Mode 2. OVERLOAD. 105% to 150%.of rated load. Constant voltage output but 10

minute timer initiated which upon expiring will shutdown the inverter. This is

long enough to cope with start up surges and current inrushes in the load.

Note. When the load exceeds 105% the static switch will normally transfer the load to

reserve (if available) so inverter overloads should be a rare occurrence.

Mode 3. CURRENT LIMIT. When the load is 150% or more of nominal then the inverter

changes to a constant current characteristic to protect itself. This can result in the

output voltage falling drastically. If reserve is available it will have transferred to

reserve immediately instead. If transfers are inhibited for any reason then the

inverter will continue in current limit until either the load subsides to normal or

the 10 minute timer expires.

STATIC SWITCH

The static switch is an automatic, solid state, changeover switch having a make-before-break

action so that no interruption to the load occurs. Therefore the inverter will be permanently

synchronised to the reserve in order to avoid phase jumps or even phase reversals to the load

at the instant of transfer. It monitors the operating status of the various parts of the UPS and

the logic will select one of two modes either INVERTER-TO-LOAD or RESERVE-TO-

LOAD.

Mode 4. INVERTER TO LOAD. This is the normal mode for the unit and is automatically

selected whenever possible.

Mode 5. RESERVE TO LOAD. Transfer to reserve occurs automatically when certain

specified abnormal conditions prevail. It returns to inverter 10 seconds after the

alarm conditions clear.

It has no moving parts, the active components being switching thyristors to preclude arcing

and sparking during switching for long term reliability. Note transfers can take place at any

place in the cycle, they do not have to be at a zero crossover.

MAINTENANCE BYPASS

For safety during maintenance and repair a wrap-around manual bypass is incorporated into

the equipment. It can be selected only by the operator not by the control logic. It provides

safety isolation of major internal parts for purposes of repair and maintenance.

4.1. HANDLING ON ARRIVAL

Unpack the equipment. Take care not to short circuit battery terminals together. Do not

discard keys, battery connectors or accessories when disposing of packing materials.

The cubicle keys will be in a bag taped to the cubicle door.Check the contents against the consignment note. The equipment has a rating plate normally

affixed inside the door panel at the front which will identify the cubicle. Report immediately

to the carrier and supplier if anything is missing or damaged. Delay in reporting may invalid

claims for free repair or replacement.

NOTE : The battery and equipment cubicle often arrive separately.

The cubicle and battery must be handled with care, keep them upright. Do not drop or subject

them to impact. Cubicles are often top heavy with offset centres of gravity.

The transit case is designed to be handled by a fork lift truck. Note the centre of gravity is

often offset and cubicles may be top heavy, so take care to position the lift forks safely.



CHLORIDE

INDUSTRIAL SYSTEMS

Page 24 of 65

The equipment may be lifted by crane. It will be necessary to pass slings underneath the

cubicle. The slings should be positioned under the extremities of the cubicle with safety straps

to prevent them slipping towards the centre when under vertical tension. Also protect

protrusions such as meters and switches from accidental damage from the lifting slings.

4.2. STORAGE

The cubicle should be stored in a clean dry environment. Although it is designed to operate in

an ambient of 0°C to 40°C it can be stored in temperatures as low as –20°C.

If it is to be stored for a long period of time some packing will be needed to prevent dirt

getting inside through grilles and openings. When storing or shipping batteries at sub-zero

temperatures the electrolyte must not be allowed to freeze otherwise mechanical damage can

occur to the plates. Freezing occurs at about –20°C. Batteries should be maintained fully

charged as this keeps the freezing point low. Follow the manufacturer's instructions.

4.3. PUTTING INTO INSTALLED POSITION

The equipment will have to be lifted from its pallet and manoeuvred into position. Note that

battery cubicles are extremely heavy and adequately strong lifting gear is needed.

Once in position adjacent cubicles should be fastened to each other by means of through bolts

(these are provided inside plastic bags inside the cubicles), and to the floor using anchor

bolts. Before fitting each anchor bolt, level the cubicles for both horizontal and vertical planes

as required using incompressible shims.

The procedure for fixing the panels together is as follows:

Take the kit comprising of 4 screws and nuts (HM6 x 70mm)Remove the 2 transfer screws on the separating panel

But the cubicles together holding the separating panel in place. The separating panel is

sandwiched between the cubicles

Take the 4 screws and open the panel doors

Put the screws through the holes in the uprights which go through the separating panel. There

are 2 at the top and 2 at the bottom. Put the nut on the screw and tighten.



CHLORIDE

INDUSTRIAL SYSTEMS

Page 25 of 65

4.4. CABLE ENTRIES

Refer to the general arrangement drawings for cable entry positions.

Cable sizes are not specified in this manual. The installer must assess the requirements of

each site with regard to the regulations and the relevant codes of practice.

Before making the connections set all power switches, isolators and circuit breakers to OFF.

Remove the battery fuse.

The incoming cables must be secured by means of a strain relief glands to the gland plate

where they enter the cubicle. The gland plate is not pierced so a suitable hole will have to the

cut for each cable entry. The gland plate must be removed from the equipment and taken

elsewhere to be drilled to prevent swarf entering the unit. The wires are then to be routed

to their respective terminals ensuring that there is enough slack to prevent strain on the

terminal. Cable runs should be cleated at intervals of 1/2 metre to rigid structure inside the

cubicle.

4.5. TERMINAL CONNECTIONS

4.5.1. Phase rotation

The equipment requires the phase rotation to be correct for correct operation. Terminals are

labelled for that purpose.

4.5.2. Battery

The battery cable should be connected with the battery fuse removed and the battery isolatorOFF. Check and double check that the polarity of the battery connection is correct. An error

here can cause major damage to the system.

WARNING: DO NOT CLOSE BATTERY ISOLATOR OR FIT FUSES

UNTIL THE FILTER CAPACITORS HAVE BEEN PRE-

CHARGED BY THE CHARGER.

4.5.3. Neutral

Within the UPS if no neutral-to-earth link is provided the UPS neutral adopts the same

potential as the incoming Reserve Neutral. Therefore if the Reserve input has no fixed neutral

the UPS output Phase and Neutral will float.

Note: Do not set up a neutral line that has two separate connections to earth because

this will set up an EARTH LOOP which can have the effect of introducing noise

into the UPS output.

4.5.4. Earth

The cubicle earth bar must be grounded to a suitable earth point.

Apart from the mandatory safety protection it provides, it also acts as a drain for spurious

noise. Consequently there is a continuous leakage to earth of several tens of mA in normal



CHLORIDE

INDUSTRIAL SYSTEMS

Page 26 of 65

operation. Therefore Earth Leakage Trips (ELT) or RCCD on the input should take into

account this small leakage.

4.6. VENTILATION

All ventilation apertures must be kept free and clean. These systems can work in a continuous

environment within 0 to 40°C temperature range, although, ideally the ambient temperature

should be below 25°C.

The heat can be removed from the equipment room by a forced cooling ventilation system or,

alternatively, an air conditioning system.

The required air changes per hour will depend on the system rating, the heat loss and the

cooling air temperature.

4.7. BATTERY-VENTED LEAD ACID

The battery is a vented lead acid type. It gives off significant amounts of gas (hydrogen and

oxygen).

A specially ventilated battery room is required.

The battery needs its electrolyte topped up routinely.

However the battery is suitable for boost charging.

4.8. BATTERY INSTALLATION

WARNING REMOVE RINGS AND METAL WATCHSTRAPS WHENWORKING ON BATTERIES. ALSO USE INSULATED TOOLS.

It is the responsibility of the installer to arrange suitable protection.

The installer will have to connect the inter-cell cables as shown in the battery diagram in

section 10 of this manual.

Before starting, remove the battery fuses and ensure the battery breaker or isolator is OFF.

BATTERY INSTALLATION CHECK LIST

Battery isolator OFFBattery fuse removed

Batteries on each group interconnected.

Voltage check of each battery group

Check no short from battery to earth

Check metal battery cubicles (or metal stands) are earthed

Interconnect the battery in accordance with Battery Diagram.

Use voltmeter to check the voltage of each half of the battery.

Terminate the cables linking the battery and the UPS. Make absolutely sure these are the

correct polarity, as an error will cause substantial damage when the equipment is started

up.

3. EVENT LOG

This module allows displaying one by one all the events memorised into the historical record, in a

chronological order.

Example of event:

To access the Event Log, select the item Event Log in the general menu of the equipment. The first

event of the list is then displayed. If no event has occurred yet, the message « No event » is displayed.

Every event is detailed as follows:

The concerned block,

The text of the detected fault or alarm,

The nature of the event (indicates if the event appeared or disappeared)

The date and time when the event occurred.

The scheduling and the memorizing of the events depend on the choice of the event mode memorizing

in the Event Log:

Saturable Mode:

The first memorised event corresponds to the first fault or alarms that occurred on the

equipment, after a UPS power on, or after a Even Log reset.

The Event Log is limited up to 100 events and any more events past this limit are memorized.

The classification of the events never changes.

N°1 : the first event which has occurred (oldest). N°100: the 100

th event.

FIFO Mode:

The first event corresponds to the fault or warning memorized occurred most recently.

Once the limit of 100 events memorized in the Event log, if a new event occurs, the oldest

event of the Event log will be removed and event which has just occurred will be memorized.

The classification of the events always corresponds to the order of which has occurred of the

events.

N°1 : the most recent

N°100: oldest. (if 100 recorded events).

5.11. OPERATING INSTRUCTIONS

5.11.1. FIRST START-UP

Starting situation: All switches, breakers and isolators are open, except both Q21 which are in‘MAINTENANCE’ position.

Check the voltage and frequency of the Reserve.

Switch on both Reserve input isolators Q31.

On both UPSs, switch charger primary supply ON. Close charger AC input isolators Q3.

Wait 30 seconds for initialisation of the chargers.

Turn both chargers on (Push Charger ON/OFF button “0/1 Charger” for 1 second until

“SWITCH ON CHARGER” is displayed on the display). If the text reads “SWITCH OFF

CHARGER”, this means the charger was already running: in this case, please push the button again to restart the charger.

Using a hand-held voltmeter, check amplitude and polarity of the charger output voltage,

on both chargers.

Also check amplitude and polarity of the battery voltage, on both batteries.

If all previous voltages are correct in amplitude and polarity, close both battery isolators

Q5.

Wait until both displays are correctly powered (no more question mark).

Operate an inverter reset on each inverter by the control push buttons (“Reset” part of the

LCD General Menu).

On both inverters, close Q24.

On both inverters, turn Q21 to ‘TEST’. After 10 seconds, both Reserve Static Switches

will be closed (visible on the synoptic diagram of the Displays).

Using a hand-held voltmeter, check that Output Distribution is correctly powered.

On each display, check the correct display of the DC voltage (Inverter Measurement

Menu) and of the AC output voltage (AC Load Measurement Menu).

If you want to check the load transfers, proceed as follows:



CHLORIDE

INDUSTRIAL SYSTEMS

Page 47 of 65

Turn both inverters on by the control push buttons (Push Inverter ON/OFF button

“0/1 Inverter” for 1 second, until “SWITCH ON INVERTER” is displayed on the

display): The inverters will not yet start.

Press S22 of INVERTER 1: INVERTER 1 will start and the Static Switch will transfer

from Reserve to INVERTER 1.

Release S22 of INVERTER 1: The Static Switch will transfer back from

INVERTER 1 to Reserve, and INVERTER 1 will stop.

Press S22 of INVERTER 2: INVERTER 2 will start and the Static Switch will transfer

from Reserve to INVERTER 2.

Release S22 of INVERTER 2: The Static Switch will transfer back from

INVERTER 2 to Reserve, and INVERTER 2 will stop.

At the end of this test, even if the inverters are not running, turn both inverters off by

the control push buttons (Push Inverter ON/OFF button “0/1 Inverter” for 1 second,

until “SWITCH OFF INVERTER” is displayed on the display).

On both inverters, turn Q21 to ‘TRANSITION’ and ‘AUTO’.

Start both inverters by the control push buttons: both inverters will start simultaneously

once you start the second inverter.

The inverters are now running in ‘AUTOMATIC’ mode.

5.11.2. MAINTENANCE PROCEDURE

Disconnecting one inverter, supposing that the load will be continuously supplied by the

other inverter (This is only possible if the total load is sure never to exceed the nominal

power of one inverter).

In this procedure, the inverter to be disconnected for Maintenance will be called

INVERTER M, and the Remaining inverter will be called INVERTER R.

Open Q24 of INVERTER M: the load is now supplied by INVERTER R alone.

On the right of INVERTER M, disconnect both SUB-D25 cables, “MC” and “FC” (cables

coming from INVERTER R), from the SUB-D25 socket. Plug “MC” into “FC”. (This will

cause an Inverter Fault and a Reserve Warning to occur on the display!)

Reset the inverter alarms on INVERTER R: Inverter block and Reserve are getting normal

again on the display.

Stop INVERTER M by the control push buttons.

Isolate INVERTER M from the Load: Turn Q21 of INVERTER M to ‘TRANSITION’,

‘TEST’ and ‘MAINTENANCE’.

Isolate INVERTER M from DC side: Stop the charger, open Q3 and open Q5. Wait long

enough to let the capacitors discharge themselves: INVERTER M is now isolated, except

the cables beyond the switches and breakers, which may remain live.

INVERTER M is now disconnected.

Before any maintenance operation, always make sure that no more voltage is presenton any part you will have to touch.



CHLORIDE

INDUSTRIAL SYSTEMS

Page 48 of 65

INVERTER R goes on running normally: it can be switched OFF and ON by the control push

buttons (if Reserve voltage is present!). It is also possible to do Maintenance operation on

INVERTER R, by following the Maintenance procedures “ Maintenance Procedure for a

stand-alone inverter ” and “ Return from Maintenance for a stand-alone inverter ” here below.

Reconnecting the second inverter (INVERTER M), supposing that the load is supplied

by one inverter alone (INVERTER R).

In this procedure, the inverter which was disconnected for maintenance will be called

INVERTER M, and the inverter which supplies the load since the beginning will be called

INVERTER R.

INVERTER R is supposed to supply the load alone, without any Warning or Fault.

Energise the DC supply to INVERTER M. Wait until the display is correctly powered (no

more question mark).

Operate an inverter reset by the control push buttons of INVERTER M.

Turn Q21 of INVERTER M to ‘TEST’. After 10 seconds, the Reserve Static Switch will

be closed (visible on the synoptic diagram of the Display).

If you want to check the load transfers of INVERTER M, proceed as follows:

Turn INVERTER M ON by the control push buttons (‘SWITCH ON INVERTER’

message on the display): The inverter will not start.

Press S22 of INVERTER M: The inverter will start and the Static Switch will switch

from Reserve to Inverter.

Release S22: The Static Switch will switch back from Inverter to Reserve, and theinverter will stop.

At the end of this test, even if the inverter is not running, turn INVERTER M off by

the control push buttons (‘SWITCH OFF INVERTER’ message on the display).

Turn Q21 of INVERTER M to ‘TRANSITION’ and ‘AUTO’.

On the right of INVERTER M, disconnect SUB-D25 cable “FC” from “MC” (cables

coming from INVERTER R) and plug these cables into the SUB-D25 socket (“MC” into

“FS” and “FC” into “MS”). This will cause an Inverter Fault and a Reserve Warning to

occur on the display, and the Reserve Static Switch of INVERTER M to be opened

(visible on the synoptic diagram of the Display).

Operate an inverter reset by the control push buttons on both inverters, in order to clear all

Warnings and Faults.

Close Q24 of INVERTER M.

Start INVERTER M: the load will be shared between both inverters.

INVERTER M is now reconnected.

5.11.3. TRANSFER TO MAINTENANCE FOR A STAND-ALONE INVERTER

Check on the inverter display that the inverter is synchronised with Reserve, and that the

Reserve voltage is ok (Message “Synchro ” is not flashing on the synoptic diagram, andReserve Status = “No Warn; No Fault”).

CAUTION: If the inverter is not synchronised AND is supplying the load, or if

the Reserve supply is not ok, do not proceed because the supply of

the load could be interrupted.

Stop the inverter: the load will be transferred without a break to Reserve.

Turn Q21 to ‘TRANSITION’, ‘TEST’ and ‘MAINTENANCE’.

Isolate the inverter from DC side: Stop the charger, open Q3 and open Q5.

Wait long enough to let the capacitors discharge themselves: the inverter is now isolated,

except the cables beyond the switches and breakers, and the complete Reserve and Bypasscabling (Q21 – L24 – Q24 – …) which may remain live.

Before any maintenance operation, always make sure that no more voltage is present

on any part you will have to touch.

5.11.4. RETURN FROM MAINTENANCE FOR A STAND-ALONE INVERTER

Energise the DC supply. Wait until the display is correctly powered (no more question

mark).

Operate an inverter reset by the control push buttons.

Turn Q21 to ‘TEST’. After 10 seconds, the Reserve Static Switch will be closed (visible

on the synoptic diagram of the Display).

If you want to check the load transfers, proceed as follows:

Turn the inverter on by the control push buttons (‘SWITCH ON INVERTER’ message

on the display): The inverter will not start.

Press S22: The inverter will start and the Static Switch will transfer from Reserve to

Inverter.

Release S22: The Static Switch will transfer back from Inverter to Reserve, and the

inverter will stop.

At the end of this test, even if the inverter is not running, turn the inverter off by the

control push buttons (‘SWITCH OFF INVERTER’ message on the display).

Turn Q21 to ‘TRANSITION’ and ‘AUTO’.

Start the inverter by the control push buttons.

The inverter is now running in ‘AUTOMATIC’ mode.

5.11.5. GLOBAL MAINTENANCE PROCEDURE

If you want to transfer both inverters simultaneously to Maintenance, in order to isolate both

inverters, please refer to the paragraphs “ Maintenance Procedure for a stand-alone inverter ”and “ Return from Maintenance for a stand-alone inverter ” here above. All instructions have

to be executed on both inverters.

5.11.6. BLACK START PROCEDURE

If you want to start the (parallel) inverters while the Reserve voltage is not present, you have

to use the Black Start option, on the front door display:

Power up the DC supply of the inverters, as described here before.

Wait until both displays are correctly powered (no more question mark).

Operate an inverter reset on each inverter by the control push buttons (“Reset” part of the

LCD General Menu).

Start both inverters by the control push buttons on each display: the inverters will not yet

start, as the Reserve Supply is not present.

On one of both inverters, on the General Menu of the LCD, choose the option “Black

Start”. Select ‘Yes’ and confirm by OK. Both inverters will start simultaneously.

Both inverters are now running in ‘AUTOMATIC’ mode. There is no memorisation of the

Black Start, so you don’t have to reset anything, once the Reserve Supply has come back.

1. Requirements and preparationsfor installation

1.1. Before installation ensure that the bat-tery room is clean and dry and is furnished

with a lockable door. The battery room must be set out and marked with warning marksaccording to EN 50272-2. Particular atten-tion must be paid to the following:

- floor load-carrying capacity and nature(conveying paths and battery room)

- electrolyte resistance of battery installationsurface

- no ignitable sources (e.g. open flame,glowing objects, electric switches) near thecell openings (500 mm ”safety distance”)

- ventilation conditions

To ensure smooth operation, coordinationbetween other persons working in the sameroom is necessary.

1.2. Check deliveries for completeness anddamage. If necessary, clean all parts before

assembling.1.3. Observe all documentation included with the delivery (e.g. battery-, rack-,cabinet-assembly drawings).1.4. Before renewing old batteries ensurethat all electric loads are switched off (sepa-rator, fuses, switches). This must be carriedout by qualified personnel.

CAUTION: Do not carry out un-authorised switching!

1.5. Open-circuit voltage measurementsof individual cells or block batteries. Ensurecorrect polarity. With unfilled and chargedbatteries these measurements can only becarried out after start-up. Fully chargedcells have the following listed open circuit

voltages at an electrolyte temperature of 20°C:

OPzS cells DIN 40736 P1 (2.08 ± 0.01) V/C

OPzS bloc batteries DIN 40737 P3 (2.08 ± 0.01) V/C

max.power cells DIN 40736 P2 (2.08 ± 0.01) V/C

solar.power cells (2.08 ± 0.01) V/C

GroE cells DIN 40738 (2.06 ± 0.01) V/C

OGi cells DIN 40734 (2.08 ± 0.01) V/C

OGi bloc batteries DIN 40739 (2.08 ± 0.01) V/C

OSP cells (2.11 ± 0.01) V/C

OSP.HC cells (2.08 ± 0.01) V/C

USV bloc batteries (2.13 ± 0.01) V/C

power.com SB / power.com HC (2.08 - 2.14) V/C

net.power (2.08 - 2.14) V/C



The open-circuit voltages of a battery’s individual cells must not deviate from eachother more than 0.02 V.The following maximum open-circuit voltagedeviations for block batteries apply:

4 V block batteries 0.03 V/block 6 V block batteries 0.04 V/block

12 V block batteries 0.05 V/block

Higher temperatures decrease, lower tem-peratures increase the open-circuit voltage.

With a deviation of 15 K from the nominaltemperature the open-circuit voltagechanges by 0.01 V/cell. Should greater deviations occur, consult the supplier.

2. Racks

2.1. Align the racks according to the instal-

lation drawing. Should an installation draw-ing be missing, the following minimum di-stances must be observed:

- To the wall: 100 mm on all sides for thecell or block container, or 50 mm for the rack.

- 1.5 metres by a nominal or component voltage > 120 V between non-insulatedterminals or connectors and earthed parts(e.g. water pipes) or between the battery’send terminals.During installation it must be ensured that DIN VDE 0510, Part 2, EN 50272-2 isadhered to (e.g.cover electrically conductive parts withinsulating mats).

- To ignitable sources: For distance from thenearest cell vent see EN 50272-2.

- To passageways: 1.5 x cell width (in-stallation depth) but not less than 50 cm.

2.2. Align racks horizontally using the le- velling parts or adjustable insulators provi-ded. The distances of the support profilesmust correspond with the cell or block bat-

tery size. Check rack stability and ensurethat all screw and clamp connectors arefirmly seated. If stipulated, earth the rack or parts thereof. Protect screw connectors fromcorrosion.Please note that when using wooden racksa flexible connector must be fitted betweeneach rack joint.2.3. Check that cells or block batteries aresound (visually, polarity).

2.4. Place each cell or block battery ontothe rack with the correct polarity. With largecells it is recommended that cell installationshould commence from the middle of therack.- Arrange cells or batteries plumb and level with the correct polarity.

- Distance between the cells should be approx.10 mm or according to the length of theconnectors supplied.

- If necessary clean the contact surface of the terminals and connectors.

- With screwed connectors:· Remove protective caps from terminals· Check

· that the terminal surfaces are properly greased with neutraliser and protectedby means of red or blue terminal cover rings,

· that the O-ring or grease groove iscompletely filled with neutraliser andthe O-ring is seated, as specified, onthe grease pad,

· that the threaded insert is sufficiently fullof neutraliser and the terminal contact surface is greased.

- Fit cell or block connectors and tighten with an insulated torque wrench(20 Nm 1 Nm). Caution: Screws areapproved for single use.

- Fit row, step, tier connectors and tightenobserving the specified torques.

- After fitting, the welded connectors of theindividual cells GroE/OGi/OPzS/OSP.HC/max.power must be aligned and

welded to the terminals as specified.Observe the specifications under VBG 15.

- If necessary, fit insulating caps onto cell/block connectors and end terminals.

- Ensure short-circuit proof installation work. Wiring with a dielectric strength and a de-signed operating voltage above the maxi-mum possible battery system voltage must be used, or a distance of approx. 10 mm

between wiring and electrically conductiveparts must be kept or the connectors must be furnished with additional insulation.

Avoid mechanical stress on the cell/battery terminals.

- If applicable, remove transport plugs andreplace with sealing plugs.

- Check electrolyte level (observe operatinginstructions/commissioning instructions).

- Measure the total voltage which shouldequal the total open circuit voltages of theindividual cells/block batteries.

- If necessary, number the cells or block bat-teries visibly (from the battery’s positiveterminal to the negative terminal).

- Affix polarity labels for the battery connectors.

- After assembly completion affix nameplateintegrated in operating instructions.

- Affix safety marking sign and operatinginstructions visibly.

The batteries must not be cleaned with fea-ther dusters or dry cloths, this could causeelectrostatic charge (explosion hazard).

3. Cabinets

3.1. Cabinets with built-in battery:- The battery cabinet is assembled on site(observing the relevant accident preven-tion rules).

- Take into account additional space neededbetween wall and cabinet for possible or planned cable entries.

- Remove any transport safety devices fromthe built-in cells or block batteries.

- Check cells or block batteries for correct position and mechanical damage.

3.2. Cabinets with separately deli- vered cells or block batteries:

- Only filled and charged cells or blockbatteries (vented or sealed) are built intocabinets.

- Assemble cabinet, place in designatedlocation and align (observing the relevant accident prevention rules).

- Place cells or block batteries into the cabi-net according to assembly plan and spa-cing specified, connect them and mark (see item 2.4).

4. CE marking

Since 01.01.97 an EC declaration of con-

formity under the low voltage regulation isrequired for batteries from 75 V to 1500 V nominal voltage with the corresponding CElabelling on the battery. The battery installer of the battery plant is responsible for issuingthe declaration and affixing the CE label onor next to the battery’s nameplate.
