3 Safety

The connection of the electrical equipment is part of the installation in readi-

ness for operation. Note that the electrical installation and the connection of the

inputs and outputs must be carried out in accordance with the local regulations.

The system must be operated by experienced personnel.

Protective earth

The protective earth must be connected before the supply cables are connected.

The system must not be operated without a protective earth.

Installation

This system must be installed by qualified specialists. Only VDE-tested and

CE-marked mains cables may be used to connect inverters to the building in-

stallation. This also applies to the connection of the loads. Do not connect any

loads to the inverter, which could overload the unit. Connecting cables should

be kept as short as possible. Connect the system using cables of adequate cross

section. Check the cables for damage to the insulation. Refer to the data sheet

for the rating of the back-up fuse. Pay attention to the polarity of the DC cable

connections. All cables must be fixed to the cable clamp rails and relieved from

stress. Check that all contacts used are securely fitted.

Hazards such as tripping, crushing, pinching etc. must be avoided.

Outbreak of fire

Dangerous voltages are present within the inverter even when fuses have

blown. For this reason, if fire should break out, do not use water to extinguish

the fire. Use sand, carbon dioxide or powder extinguishers.

Personnel training

All personnel must be trained in how to shut down the system in an emergency.

To isolate the unit in an emergency, the main fuse in the mains input and the

battery fuse (battery cabinet or external rack) must be removed. The system

must be operated by trained (experienced) personnel.

3.1 General safety instructions

These operating instructions and the safety instructions contained there-

in must be carefully read before the system (also referred to as the in-

verter) is installed or put into operation. The operating instructions must

always be kept close to the unit for later reference.

Installation, operation, maintenance and repair of the inverter sys-

tem may only be carried out by qualified and trained specialists.

You must be absolutely sure that L and N and the polarity of the battery

connections are correct, as any incorrect connections will cause damage

to the system.

Make absolutely sure that the battery is not earthed. Neither the plus nor

the minus pole must be earthed (battery floating).

Earth faults on unearthed batteries necessitate a protective device for

each pole.

Units must be fitted in the rack in the following order. The SBS is al-

ways fitted at the extreme right-hand end of the rack, the MBS on the

left next to the SBS, and the inverters must be fitted from left to right.

Even when the inverter is switched off, components within the system

are live as long as the supply network and/or battery and connected.

Live parts are exposed when you open the housing or remove covers;

danger to life if touched! Refit the covers properly on completion of the

work.

BENNING takes no responsibility for consequential damage caused by

work incorrectly carried out on the inverter system.

High fault currents (leakage currents):

A proper earth connection must be ensured before the mains is connect-

ed!

This inverter complies with norm EN 55022 Class B

This is a product for commercial and industrial use in the second envi-

ronment. Restrictions regarding the installation or additional measures

may be necessary to prevent interference.

A suitable isolating device must be provided in all supply circuits.

It must be possible to disconnect all poles of the battery supply.

As standard, the inverter system is suitable only for mounting on fire-

resistant surfaces.

Unused module slots must be fitted with a blanking plate. (Part No.

514414)

CAUTION! The electronic changeover device (SBS) may only be removed from the

rack if the manual bypass switch (MBS) is logged on.

CAUTION! Initially withdraw modules from the rack by 50 mm (plug disconnect-

ed). Then wait for at least 10 seconds. Only then remove the units com-

pletely from the rack.


INVERTRONIC compact

31.05.17

15/102 4600 en

CAUTION!

An inverter system with an SBS may only be used on earthed networks. Once

the unit has been installed and commissioned, the earthed mains point or neu-

tral conductor must not be disconnected. The neutral conductor of the bypass

supply and the neutral conductor of the load must always be linked in the in-

verter system.

In inverter systems without SBS, the neutral conductor of the inverter output

must be connected to the protective conductor terminal. If an SBS is fitted to

such a system retrospectively, this link must be removed and the requirements

for an inverter system with SBS apply.

For connecting the INVERTRONIC compact, terminal strips for power con-

nections (mains, load, battery) are provided in the bottom third of the cabinet.

Access to the terminals is obtained by undoing the screws and removing the

front protective covers.

The cables can be routed to the cabinet from all four sides and fed in through

the cabinet bottom. A double floor in the installation area is not absolutely es-

sential. Please refer to the following tables and drawings for information on

where the cables are to be connected and what size they must be in accordance

with DIN VDE 0298.

You must be absolutely sure that the neutral conductor and the phase sequence

of the bypass supply and the polarity of the battery connections are correct, as

any incorrect connections will cause damage to the system.

Be sure to refit the front protective covers when assembly is complete.

A clear inscription, which provides adequate information as to how the

whole installation is to be isolated, must be fitted to every isolating de-

vice.

Be sure to observe all the safety instructions!

personnel as defined by the norm EN62040-1-2).

If the isolator for the supply cable is not located in the same room as the

inverters, a warning notice must be attached to the inverters with the in-

scription:

Dangerous voltages are present within the inverters. The unit must only be

opened by qualified personnel.

CAUTION! Initially withdraw modules from the rack by 50 mm (plug disconnect-

ed). Then wait for at least 10 seconds. Only then remove the units com-

pletely from the rack.

Caution: A dangerous voltage is still present on the battery isolator (BCB)

when the inverters are withdrawn.

In order to avoid any accidents, it is essential to follow the instructions below:

• Do not operate the inverter if the temperature and humidity exceed the specified maximum values.

The inverter must be earthed.

3.1.2 Product safety

• The electrical supply cable must be protected by a backup fuse, which is accessible at all times.

• Do not install the inverter in the vicinity of liquids or in an environment with too high humidity.

• Do not allow liquids or foreign bodies to get into the system.

• Do not cover the air vents of the inverter.

• Do not subject the inverter to direct sunlight or other sources of heat.

• Units must be fitted in the rack in the following order. The SBS is always fitted at the extreme right-hand end of the rack, the MBS on the left next

to the SBS, and the inverters must be fitted from left to right.

3.1.3 Special safety measures

Be sure to observe the connection instructions in this manual. Check the infor-

mation on the equipment rating label. This must correspond with your electri-

cal supply network and the total power demand of the connected unit.

If the inverter should be put into storage before use, make sure that the storage

location is clean and dry. The storage temperature must be in the range -10°C

to +45°C. The inverter has been designed for normal ambient conditions such

as those stated in Chapter 6.1.5 under installation altitude, operating tempera-

ture and relative humidity, and for the stated transportation and storage condi-

tions.

Although correct operation is guaranteed if the inverter is operated at the limits

of the specified values, the life of some components may be shortened.

Special protective measures must be taken if unusual operating conditions pre-

vail:

• Moisture, steam, saline environment, dripping water or outdoor installa-tion,

• Explosive mixtures of dust and gas

• Severe temperature fluctuations

• Poor ventilation

• Heat conducted or radiated from other heat sources

• Strong electromagnetic fields

• Radioactivity which exceeds the natural level of radiation

• Fungi, insects, parasites, etc.

3.2 Transport and storage

The inverter must only be transported to the intended location in its original

packaging. The same applies for removals or returns. The unit must only be

transported and stored in an upright position. Make sure that the unit is shipped

in the correct transport position and take the centre of gravity into account. In

the case of inverter systems, slight changes in position can lead to the units

suddenly toppling due to the heavy weight. It must also be ensured that the

units have a firm footing when placed in storage.

The unit is delivered complete from the factory. The unit must always be trans-

ported in an upright position. If the unit is transported with a forklift truck, then

the forks must always be applied from the rear of the unit so that the front door

with its instruments is not damaged.

Figure 2: Transporting with forklift truck and crane

Unpacked units must only be transported in a closed lorry. The units must al-

ways be securely anchored to prevent them from slipping or toppling over. In

particular, it must be ensured that the paintwork is protected against scuffing

and scratching. Lifting belts must be used when transporting the unit in an un-

packed state. These must be positioned so that the instruments and switches on

the front door cannot be damaged.


INVERTRONIC compact

31.05.17

20/102 4600 en

The information shown in Figure 3 must be observed when transporting the

unit using lifting eyes.

Figure 3: Use of lifting eyes

Lifting eyes must only be used with the protective cover and bolts re-

moved.

When the units have been unloaded on site, they must be inspected immediate-

ly for possible damage. It must also be checked that all parts according to the

packing list are present. In the event of damage, the responsible party must be

identified – if possible – and in all cases a written report must be immediately

sent to the supplier/manufacturer (within 6 working days).


INVERTRONIC compact

31.05.17

21/102 4600 en

3.2.1 Storage of inverters

The ability of the units to be stored depends on the selected packaging.

Units with short-term packaging should be unpacked immediately on arrival at

the intended location and stored in a suitable place. In doing so, the tempera-

ture must not be allowed to drop too low or condensation allowed to form.

When the units are placed in store, the doors should be opened for a few hours

to allow the units to adapt to the new temperature without the formation of

condensation. If the units are placed into interim storage for an extended peri-

od, they must be covered with film and inspected for condensation from time to

time.

When units are supplied with long-term packaging, they must be stored in this

packaging. When doing so, the packaging must first be checked for damage.

3.3 Maintenance, service and faults

CAUTION! – Risk of electric shock!

Even when isolated from the mains supply, the inverter is still connected to the

battery circuit and is at a dangerous voltage potential. Therefore, disconnect the

battery circuit and check that the equipment is dead before carrying out service

or maintenance work.

Work may only be carried out on batteries by persons with the appropriate spe-

cialist knowledge of the required safety rules and must be supervised. Unau-

thorised personnel must be kept away from batteries.

The following safety rules must be observed when working on inverters:

• Wristwatches, rings and other metal objects must be removed

• Use only insulated tools

• Inverters must not be dismantled

If you require a system check at regular intervals for safety reasons, e.g. an an-

nual inspection, then please contact us. We will be pleased to submit a quota-

tion for an appropriate contract.

5 Introduction

This manual provides information on the INVERTRONIC compact inverter

system, their principle of operation and the action to be taken in the event of

operational faults. This manual also contains information relating to the trans-

portation, storage, handling and installation of inverter systems. The planning

guidelines in this manual relate only to the special requirements of inverter sys-

tems. It is essential that the national and local regulations for electrical installa-

tions be followed when installing the equipment.

The content of this manual may change due to advancing technology. We have

strived to make the content as correct and clear as possible. If errors should

have occurred however, we would be grateful for information provided to up-

date on the next release.

We accept no liability for errors in this manual and for consequences resulting

therefrom.

The inverter system (inverter) is designed to protect sensitive electrical equip-

ment against interference, which can occur due to poor current/voltage quality,

or even loss of supply. Sensitive systems require comprehensive protection

against electrical faults.

These can be external faults (e.g. thunderstorms, operational faults) or interfer-

ence from adjacent equipment (e.g. motors, welding systems etc.). Mains faults

can be summarised as follows:

• Fast and slow mains voltage peaks and variations

• Mains failure

• Fast and slow frequency peaks and variations

• Signals or transients superimposed on the supply

The inverter system conditions the mains voltage and ensures a constant output

voltage.

When the inverter is in operation, mains interference is therefore kept away

from operationally critical equipment, and software and hardware cannot be

damaged.

CAUTION!

THE INVERTER MUST ONLY BE INSTALLED AND OPERATED BY QUALIFIED PERSONNEL.

5.1 General principle of operation

The inverter system from the INVERTRONIC compact product family is a

compact AC power supply for widely differing applications in the telecommu-

nications and industrial fields. The different system configurations enable the

system to be matched to the specific requirements.

Depending on the design, the output power of the inverter system can be ex-

panded in 1000VA (24Vdc) or 2000VA (48 and 60Vdc) increments by plug-

ging further inverters into the shelf’s. The nominal DC input voltages can be

24Vdc, 48Vdc or 60Vdc.

System states can be set up and read off on the SBS LCD display. It is possible

to display measured values for the mains supply, the loads and the individual

system components.

With the help of a manual bypass switch (MBS), the inverter system can be

maintained, expanded and repaired without interrupting the supply to the con-

nected loads.

The inverter system is controlled and monitored by digital signal processors

(DSP), which are programmed with appropriate algorithms.

Individual components communicate with one another by means of a CAN-

BUS system (Controller Area Network), which guarantees a high level of im-

munity against interference.

By means of serial interfaces, the system states can be determined when carry-

ing out a service, and during software updates.

Widely differing systems with regard to power, freedom from interruption and

redundancy can be assembled using the individual components of the inverter

system in a similar way to a building block system.

Only inverters with the same KVA rating, input voltage and output voltage can

be connected in parallel.

Up to 5 inverters can be connected in parallel in an appropriate shelf without an

SBS and MBS.

Figure 5: Single and parallel operation of maximum 5 inverters in one shelf

In the case of simple parallel operation of inverters, the maximum system pow-

er is 8kVA (24Vdc) or 16 kVA (48 and 60Vdc). Here 8 inverters are connected

in parallel divided between 2 equipment shelves.

With parallel operation, it is essential to ensure that the shelfs are

mounted one above the other.

A Manual Bypass Switch (MBS) is always incorporated in all inverter

systems with a Static Bypass Switch (SBS). This enables the system to

be maintained and repaired without interrupting the supply to the loads.

System description

The INVERTRONIC compact inverter system is a compact AC power supply

for different applications in the telecommunications and industrial fields. The

various system configurations enable the system to be matched to the specific

requirements.

The output power of the inverter system can be extended in 1000 VA steps for

an input voltage of 24Vdc or 2000 VA for an input voltage of 48Vdc or 60Vdc

by inserting inverter modules (INV). The inverter system is controlled and

monitored by digital signal processors (DSP).

Individual components communicate with one another by means of a CAN-

BUS system (Controller Area Network), which guarantees a high level of im-

munity against interference.

7 INVERTRONIC compact system description

7.1 System configurations

Different systems with regard to power, freedom from interruption and redun-

dancy can be assembled using the components of the inverter system.

The simplest systems are single operation (1 inverter) and the parallel opera-

tion of several inverters without electronic changeover device (SBS, ECD).

Only inverters with the same input and output voltage can be connected in par-

allel.

Up to 5 inverters can be connected in parallel in an appropriate shelf.

In the case of parallel operation of inverters, the maximum system power is

15.0 kVA or 30kVA. Above are 15 inverters connected in parallel divided be-

tween 3 identical shelves.

In order to increase the reliability of the supply to the loads, an SBS can be in-

corporated into the inverter system. Three inverters, one SBS and one MBS can

then be installed in a shelf accommodating these modules. They are installed in

the right two positions in the shelf. The maximum number of inverters is re-

duced to 13 modules. The maximum system power is 13.0 kVA for the 24Vdc

module or 26kVA for the 48/60Vdc type modules.

A shelf with SBS and MBS positions is always incorporated in all inverter sys-

tems with an electronic changeover device. This enables the system to be main-

tained and repaired without interrupting the supply to the loads. A system con-

figuration with SBS and MBS is recommended as the default configuration on

account of the increased reliability of the extended measuring and control func-

tions.

7.2 INVERTRONIC compact inverter system components

The system comprises the following main components:

7.2.1 Inverter

Abluft

Exhaust air Zuluft

Ventilation

Figure 24: Inverter module

General - The direct voltage is converted into a single-phase alternating voltage

with constant amplitude and stable frequency in the inverter. A high efficiency

is achieved even in the partial load range using pulse width modulation and

IGBT power transistors. The failure of a component or the power stage does

not lead to an interruption in the supply to the load. The inverter is disconnect-

ed from the busbar and the load is switched to the mains supply without inter-

ruption by means of the electronic changeover device. A fault is indicated at

the same time.

Output - The waveform (sine wave) of the output voltage is controlled by

means of software by a microcontroller (DSP = digital signal processing). This

keeps the distortion factor low, particularly in the case of a non-linear load.

The output is fed via filter circuits and protected by a fuse. In the event of a

short circuit, the short-circuit-proof inverter delivers a short-circuit current of

>250% and switches off and remain off after 4 seconds.

Neutral conductor - The neutral conductor of the inverter output is electrically

isolated from the inverter enclosure.


INVERTRONIC compact

31.05.17

46/102 4600 en

Frequency control - The inverter output frequency is controlled by a PLL,

which depending on the operating state of the system, guarantees synchronisa-

tion with the internal clock pulse, the mains supply (only when an SBS/ECD is

provided) or parallel inverters.

If the controlling frequency (bypass supply) deviates by more than the adjusta-

ble value of a minimum of ± 1% and a maximum of ± 5%, the system switches

to the internal clock pulse and then ensures that the frequency remains constant

± 0.1%.

Ventilation

Figure 25: Electronic changeover device (SBS)

The electronic changeover device (static switch) consists of two static micro-

processor-controlled (DSP) thyristor modules (2 anti parallel thyristors) in the

mains bypass and in the inverter path. If the output voltage deviates from the

set values by an appropriate amount (e.g. in the case of an inverter fault), they

switch the connected loads automatically and without interruption to the bypass

supply. The bypass has an overload capability of 120% for 10 min and 1000%

for 10 ms.

The static switch automatically switches the load back to the inverter when

normal operation is resumed (e.g. after an overload or a short circuit).

In synchronous mode, the changeover from inverter to mains and back again

takes place absolutely without interruption at a zero crossover.

The thyristors are fused in the connection panel.

8 Electrical connection

CAUTION!

A dangerously high battery voltage exists inside the unit even when the mains

voltage is switched off! All connection and commissioning work must only be

carried out by a skilled electrician. Before starting work on the system, this

specialist must familiarise himself with the particular features of this inverter

range by reading the manual and the installation instructions. All requirements

for the environmental and operating conditions listed in the technical data must

be adhered to in order to guarantee trouble-free operation of the inverter.

For connecting the INVERTRONIC compact, terminal strips for power con-

nections (bypass, load, battery) are provided in the cabinet. The cables can be

routed to the cabinet from all four sides and fed in through the cabinet bottom.

A double floor in the installation area is not absolutely essential. Please refer to

the following tables and drawings for information on where the cables are to be

connected and what size they must be in accordance with DIN VDE 0298.

Cabling to and from the inverter system must only be laid by qualified

specialist personnel.

It is imperative that the safety instructions in Chapter 3 be observed.

Make absolutely sure that the battery is not earthed. Neither the plus nor

the minus pole must be earthed (battery floating).

Make absolutely sure that L and N and the polarity of the battery con-

nections are correct, as any incorrect connections will cause damage to

the system.

Units must be fitted in the rack in the following order. The SBS is al-

ways fitted at the extreme right-hand end of the rack, the MBS on the

left next to the SBS, and the inverters must be fitted from left to right.

Please first check the configuration level of the inverter system to be in-

stalled. Be sure to pay attention to the enclosed terminal diagrams and,

in case of doubt, compare these with the markings on the connecting

terminals.

8.1 Behaviour under special operating conditions

8.1.1 Overload

The inverter can supply 200% of its rated power for 4 seconds, 120% for 60

seconds and 110% continuously. For higher overload, the system switches to

bypass. If the bypass mains supply is not available, the inverter switches off af-

ter 4 seconds.

(→ red LED illuminates and green LED flashes)

8.1.2 Short circuit on load bar

A short circuit occurring in the downstream load network must be switched off

within max. 10 milliseconds to ensure that the other loads can continue opera-

tion without disruption.

In this case, the inverter system switches immediately to bypass so that the up-

stream load fuse can blow.

If the short circuit occurs during battery operation and if the bypass mains sup-

ply is not available at that time, the output current is limited to 2.5 x rated cur-

rent (standard).

8.1.3 Mains supply not in tolerance

In normal operation, the inverter is synchronised with the mains supply. As

soon as the mains frequency goes outside the tolerance range (standard ±5 %),

the inverter switches to the internal clock pulse. The return to normal operation

is initiated by the control system.

8.1.4 System faults

Inverter If a fault occurs in the inverter, the system switches to bypass without any in-

terruption.

Battery If the battery voltage becomes too low, the inverters switch off and the loads

are fed from the bypass supply.

8.1.5 Fan failure

In the event of a fan failure, the inverter provides its output voltage until the

overtemperature trip level is reached. After this, the system switches to bypass

without interruption.

Check the installed cable cross sections when upgrading the inverter

system. The cable cross sections must be changed to suit the upgrade.

Earth faults on unearthed batteries necessitate a protective device for

each pole.

The earth connection must be made first in accordance with VDE DIN. There

is no need to follow a particular installation sequence.

8.3 Bus connection

For reliable and fault-free operation of the inverter systems, the CAN-Bus must

be "terminated" on the back panel cards. This is achieved by fitting jumpers in

defined positions.

Complete systems are fully configured in the factory for the cus-

tomer's specific requirements. The bus connection is only required

when re-configuring or replacing an shelf.

CAUTION! Have all the inverters and the electronic changeover device been set up

for the same voltage and frequency?

Have all device settings been made and checked?

• If a manual bypass switch (MBS) has been installed as a separate

assembly, move the switch to Position 1. The manual bypass switch

must always be fitted directly on the left of the electronic changeo-

ver device (SBS).

• Slot the electronic changeover device into the extreme right-hand

position of the appropriate shelf. The front panel must be flush with

the frame of the shelf.

• Slot the inverters into the shelf. The order and positions can be

chosen at will. The front panel must be flush with the frame of the

shelf.

• Cover all free slots with a blanking plate.

• Screw all units and blanking plates to the shelf.

All the electrical connections are automatically made when the units are slotted

into the shelf.

It is imperative that the safety instructions in Chapter 3 be observed.

The upstream isolators must be opened in order to isolate the inverter

system from the supply sources (to make it completely dead).

If an emergency stop or EPO circuit is to be implemented, these circuits

must be additionally installed externally. Approved isolating devices

must then galvanically isolate all AC and DC inputs (AC supply and

battery inputs).

9 Configuring the inverter system

CAUTION! The safety instructions must be observed at all times during installation,

connection and commissioning.

When the inverter system has been assembled, connected and commissioned,

all the components are fully ready for operation. No additional settings or ad-

justments are necessary during operation under any operating conditions.

When choosing a location for the inverter system, it must be ensured that the

floor is firm and level. The inverter system is designed for use in closed and

dry rooms. The maximum permissible ambient temperature is 40°C (see Tech-

nical Data). During installation, it must be ensured that the inverter system is

not exposed to aggressive substances and the passage of cooling air is not

hampered.

CAUTION! Any changes to settings must only be made by trained and qualified

personnel. The modified inverter system settings must be available at

all times. Only then is it possible to obtain an overview of the current

system configurations. This simplifies the specific replacement of

components and fault diagnosis.

All inverter system components are set up in the factory to the values and oper-

ating modes specified by the user or to default values. No changes to the set-

tings are necessary for correct operation.

If, however, system configurations are changed or new systems are configured

from individual components, or components are replaced or added, some set-

tings and functions must be checked.

Shelfs

The types of shelf may vary depending on the required system configuration.

In order for the CAN-Bus system to work without any problems, the cable ends

of the CAN-Bus system must be fitted with a termination resistor/jumper on

each shelf in accordance with a defined scheme. In addition, the shelfs must be

suitably connected by means of data cables.

These measures are only required in the event of a completely new inverter

system design. As this is only rarely undertaken by the user, it will not be de-

scribed in more detail.

Electronic changeover device configuration (SBS)


INVERTRONIC compact

31.05.17

65/102 4600 en

Every electronic changeover device is set up in the factory to the values speci-

fied by the user or to default values. The values set can be seen from the con-

figuration data sheet and the equipment marking.

• System voltage; permissible voltage tolerance

• Frequency, permissible frequency tolerance

• Operating mode "Inverter priority" or "Mains priority"

Inverters

Every inverter is set up in the factory to the values specified by the user or to

default values. In the case of an inverter system without electronic changeover

device, these values cannot be changed. The values set can be seen from the

configuration data sheet and the equipment marking.

• Output voltage

• Frequency

• Switching thresholds for the input voltage monitoring

Changing these values using the display and operating menu of the electronic

changeover device is described in more detail in chapter 6.

These settings should be checked and changed if necessary before fitting the

units.
