(12Volts @ 5 Amps)

GENERAL INFORMATIONThis sophisticated switch-mode charger has been specially

developed for use with all deep-cycle sealed lead-acid batteries including “Dryfit” gel batteries. It is light-weight, compact and efficient. It will operate on any AC input voltage between 110VAC to 260VAC - this means it will work ANYWHERE in the world without an additional transformer or switching for the 1204/5 . It automatically charges, without requiring monitoring, all sealed lead-acid, maintenance type and gel batteries with a nominal voltage of 12. Charging begins immediately if the battery has been properly connected and AC power turned on.

The output of the charger is electronically protected against short circuit, reverse polarity connection and extremely deeply discharged batteries. A three colour Light Emitting Diode (LED) on the front panel is used as a charging and state of charge indicator.

OperationIMPORTANT! Connect the charger to batteries before turning on.

Plug in and switch on charger at the mains supply and then turn the charger’s POWER switch on located on the back panel --charging should begin.

When charging a flat battery, the charging indicator LED illuminates RED. After reaching approx. 80% charge, the charging LED will turn YELLOW, when 100% the LED will be GREEN.

NB A deeply discharged battery may take some time before it draws enough current to cause the LED indicator to change colour. If you are sure the battery is flat, just leave the charger connected until indication begins. If the battery still refuses to charge have it checked at your place of purchase.

YOU MAY LEAVE BATTERIES ON CHARGE UNTIL READY FOR USE.

If the battery you are charging is too large for this charger, a safety timer will reduce the output voltage after 1 hour at the gassing voltage.

If the battery is removed from charge the output current stops immediately. To resume normal charging operation, turn charger off, re-connect and turn on.

To ensure a full charge in the shortest time and ensure the longest possible battery life, make sure all leads and connectors are clean and undamaged.

1. Check all connections throughly and that the power switch of charger and the AC mains are turned ON.

2. Check that connectors on lead from charger to battery are correctly wired i.e. RED to positive (+) and BLACK to negative (-).

3. During the first charging phase, the charger may become quite warm or slightly hot to touch -- this is normal if charging deeply discharged batteries.

UNDER NO CIRCUMSTANCES attempt to use the charger if the AC power cord or the DC leads are damaged. These must be replaced by a suitably qualified repair station or return to your place of purchase for service.

Read these installation and operating instructions before connecting and using the IUOU charger.

Charging

The three (3) phase IUOU charge characteristic guarantees rapid, complete and at the same time gentle charging of the battery

1. Stage: CC-Phase. The battery is charge with constant current until the maintenance voltage is reached. The control LED lights red.

2. Stage: UO-Phase. Reaching 80% of constant current the voltage switched over to boosting voltage. That means constant high charging voltage until the current reached 10% of maximum current or cross the time limit of 2 (4) hours. The LED lights yellow.

3. Stage: U-Phase. After the UO-phase the charging voltage switched over to floating voltage. In this phase the battery is practically at rest and only takes the current necessary for maintenance capacity. The LED lights green.

If a load is connected to the battery in this phase it is possible that the charger switches back to the UO-phase until 2 hours time limit is reached. Otherwise it remains in this U-phase.NB time out timer can be adjusted to 1, 2, or 4 hours.

CAUTION! Batteries with a shorted cell must not be charged, as there is the danger of explosion through the occurrence of electrolytic gas.

The IUOU Compact chargers applied to following standards:

Locate the temperature sensor in such a position that it cannot be influenced by other heat sources (e.g. Hot-air or cooler hose). Plug in the 3.5mm plug into the back panel socket, the IUOU charger will automatically switch over to temperature controlled charging characteristic.

! The temperature sensor must be connected to the socket on the rear panel of the charger.

The IUOU charger can be used as a main unit provided that maximum current consumption of the consumers does not exceed the current rating of the charger. It is recommended always to connect a battery (fig. 2). The consumers should be connected direct to the battery.

This applies in particular to consumer with high peak currents (e.g. high start-up current in the case of compressors).

In parallel operation (consumer and battery), the maximum consumer current should be less than the rated current of the chargers because otherwise the battery will discharge.

Locate the temperature sensor in such a position that it cannot be influenced by other heat sources (e.g. Hot-air or cooler hose). Plug in the 3.5mm plug into the back panel socket, the IUOU charger will automatically switch over to temperature controlled charging characteristic.

! The temperature sensor must be connected to the socket on the rear panel of the charger.

The IUOU charger can be used as a main unit provided that maximum current consumption of the consumers does not exceed the current rating of the charger. It is recommended always to connect a battery (fig. 2). The consumers should be connected direct to the battery.

This applies in particular to consumer with high peak currents (e.g. high start-up current in the case of compressors).

In parallel operation (consumer and battery), the maximum consumer current should be less than the rated current of the chargers because otherwise the battery will discharge.

Battery chargers EPS 600 and EPS1000 are modem fully automatic devices suitable not only for charging but also for maintaining and monitoring the batteries. Charger stores data about charging times and Ah counting. This data may be accessed for further analysis.The charger may be used as a stationary device or can be installed and operated in the vehicles. Charger should be mounted horizontally. Any drilled holes or any mechanical changes of the housing may damage the charger.

Your EPS battery charger was factory programmed for a specific battery type. Make sure the charging profile suits your battery type. To change the charging profile for a specific battery type, parameters may be programmed with a PC software package and a programming interface. The programming parameters allow the charger' s profile to suit the battery type. Up to five charging phases can be programmed. The charging voltages, currents, charging times, temperature compensation and other control functions can be programmed. Please contact your dealer for further information. By programming the charging profile always follow the battery producer instructions regarding voltages, currents and charging times.

Read the operating instructions carefully before using the EPS Battery charger.

Note: Please note, that new batteries reach the maximum capacity after multiple charging cycles have been completed successfully. Old batteries often don't reach the full capacity. This can cause the charging process not to end properly (example:maximum charging time overflow).

TO START THE CHARGING PROCESSEstablish a safe connection between the battery and charger first. Then plug the mains connector. This sequence must always be followed in this order. When removing the connection, remove the mains plug from the mains first before disconnecting the battery circuit.After connecting the battery, the red LED (error LED) flashes several times and then remains OFF. By starting the charging the yellow LED lights ON (also a click the inside relay can be heard and cooling fan starts to operate).

Whenever you are handling or working with a lead-acid battery, consult your battery owners' manual for instructions and safety precautions.

COOLING FANDo not cover the cooling fan openings to ensure enough cooling flow. Otherwise the charging current will drop and the charging time will increase proportionally.Use the charger for the defined battery type only, (according to the parameters). If the charging profile does not suit the battery type, the battery will not be charged properly and the life time of the battery may be shortened.

BATTERY TYPEUse the charger for the define battery type only, (according to the parameters). If the charging profile does not suit the battery type, the battery will not be charged properly and the life time of the battery may be shortened.

GASLead-acid batteries produce hydrogen-oxygen gases which can be explosive and sulfuric acid that can cause severe burns. Make sure working area is well-ventilated. Cigarettes or any open fires or sparks may cause anexplosion. Keep all ignition sources away from the battery.

ACIDBattery acid can severely damage your eyes and skin. In event of accident, flush with water and seek medical help immediately. Use proper personal protective devices when handling a damaged or leaking battery. Treat material used to clean up a battery acid spill as hazardous waste.

TOXIC SUBSTANCESBatteries contain hazardous materials. Among others lead and antimony are toxic substances. Waste lead-acid batteries are hazardous waste and must be treated according to the Battery Disposal Regulations.

Description of the drawings:

1. 230V plug

2. Battery connector: red = Battery (+) black = Battery (-)

3. Temperature sensor (see the following table)

Any temperature sensors used are only active if the battery charger temperature compensation parameters have been set to values other than zero. We recommend to fix the temperature sensor to one of the battery terminals.

The charger EPS 1001 can be delivered with two separate outputs. The two outputs have no galvanic connection. In case of for example 24V charger with two outputs, they may serially be connected to a 48V string of batteries (each one to 24V string). With this option the batteries get better charge equalization. When viewing the charger from the rear, where the battery cables exit the housing, the output number one is in the middle and output number two at the top.

SYMPTOMS WHEN THE CHARGER IS POWERED AND IS BEING USED AS A DC POWER SUPPLY / UPS

THE VOLTAGE DROPS WHEN LOAD IS SWITCHED ON

The load is trying to draw current more than the current limit value of the charger ( the current limit value is the maximum specified charging amps ). Once the load current reaches the current limit value, the current limit circuit is activated and the output voltage drops. Some loads like motors, compressors, incandescent lamps, halogen lamps, heating elements, relays, coils, capacitors etc. draw very large inrush/starting currents which may reach up to 10 times their normal operating currents. Ensure that the starting / inrush current or the maximum operating current of the load is lower than the current limit value of the charger.

Both the AC side and DC sides have fuses that are located inside the charger. Disconnect the AC power when checking or changing the fuses. Open the charger as follows: 1. Remove the 4 screws on the ammeter side of the top cover 2. Gently slide the top cover out by about 2 to 3 inches. (CAUTION ! The top cover will

be restrained from fully sliding out by the wires connecting the ammeter , LED and fan) 3. The fuses will now be accessible FUSE RATINGS:

Using the inverter Sine Wave lnverter

Warning! In order for the integrated residual current-operated protective device of the 150S-12A/E and 150S-24A/E inverters to work properly, the earth connection of the inverter (fig. 5.1, page 4)

must be electrically connected to the chassis of the vehicle or boat.

Lay the flexible earth cable from the earthing point of the vehicle to the earthing point of the inverter. Connect the earth cable to the chassis terminal (fig. 5.1, page 4).

Warning! Reverse polarity connection of the battery wires can damage the inverter. Do not use the inverter with electrical systems using pos itive ground.

8 Using the inverter 60S-12A/E, 60S-24A/E, 100S-12A/E, 100S-24A/E: Always connect only one consumer unit to the 115V or 230 V socket on the front of the device. 150S-12A/E, 150S-24A/E: Always connect max two consumer unit to each of the 115V or 230 V sockets on the front of the device. Switching on Operation is done with the ON/OFF-switch at the front side of the inverter. In switch-mode ON the LED control ”Power” illuminates. Malfunctions Does the battery voltage fall below 10.7 V (60S-12A/E, 100S-12A/E, 150S-12A/E) resp. 21.4 V (60S-24A/E, 100S-24A/E, 150S-24A/E), the LED control „OVER-LOAD“ (fig. 6.3, page 4) illuminates and an audible signal is given. The inverter switches off automatically in case of a battery voltage down to 10 V resp. 20 V. 12

Sine Wave lnverter Cleaning and caring for the inverter If the device overheats, the inverter switches off – the “OVER TEMP” LED (fig. 6.2, page 4) lights up.

If this happens, switch off the inverter using the switch. Ensure that the inverter is sufficiently ventilated Wait for approx. 5 - 10 minutes and switch on the inverter only.

When operating the inverter at high load for lengthy periods, it is advisable to start the engine in order to recharge the vehicle battery. 150S-12A/E, 150S-24A/E: If a residual current of more than 30 mA flows through the earth wire, e. g. in the case of an accidental short circuit, the integrated residual current-operated protective device automatically switches the inverter off within one second.

If this happens, switch the inverter off with the switch. Rectify the fault. Switch the inverter on. The inverter is ready for operation again.

9 Cleaning and caring for the inverter

Caution! Do not use sharp or hard objects for cleaning as these may dam- age the device.

NOTE!-VOLTAGE READINGS ON NO LOAD

The output has one common negative terminal and three positive terminals for charging 3 banks of batteries. Each positive terminal has an internal isolating diode in series which has a forward voltage drop of 0.8 to 1.1 V. On no load ( that is when no battery or other dc load is connected to any of the 3 terminals ) , the voltage reading will read 0.8 to 1.1 V higher than the specified float voltage. Note that the specified float voltage is at a load of 1 A. Also, the voltage on the terminals not connected to the load ( for example, when one bank of battery is connected to one positive terminal, the other 2 positive terminals will remain disconnected ) will read 0.8 to 1.1 Volt higher than the voltage of the loaded terminal.

These chargers can be manually selected to operate in 3 stage or 2 stage modes ( Please see “Selecting the Type of Battery and Charging Stages” at page 7) . The charging stages are described below :

STAGE 1 -CONSTANT CURRENT OR BULK CHARGE STAGE When the battery is low, it will try to draw larger charging current. The charger senses the current draw and limits this to the maximum permissible value (15A for EC-315 / EC-340 and 30A for EC-330). Bulk charging takes place at this constant current. In this condition of constant current, the voltage measured at the charger or battery terminals will be the battery’s own voltage. The constant current injected into the battery starts restoring the battery capacity and it’s voltage starts rising. When this voltage approaches the threshold of battery “gassing”, termed “Boost or Absorption Voltage”, the charger automatically switches over to Stage 2 - “Boost or Absorption Stage”. The value of this voltage depends upon the type of battery being charged (See Dip Switch Settings). By this time, approximately 80% of the battery capacity will normally have been restored (Note: The percentage capacity restored till the point the battery reaches the boost or absorption voltage is inversely proportional to the value of the bulk charge current.)

STAGE 2 - CONSTANT VOLTAGE BOOST OR ABSORPTION STAGE As explained above, when the battery voltage approaches the point where battery “gassing” can begin, the charger automatically switches over to the “Boost or Absorption Stage”. The charger applies a constant voltage whose value depends upon the type of battery selected ( See Dip Switch Settings ). This controlled overcharge restores the balance 20% of the capacity in a minimum amount of time. As the capacity is fully restored, the charging current starts reducing. When the current reduces below the preset threshold, the charger automatically switches to the “Float or Maintenance Stage”.

STAGE 3 – CONSTANT VOLTAGE , FLOAT OR MAINTENANCE CHARGING STAGE As explained above, as the charging current drops below the preset threshold (1.5 to 2 Amps for EC-315 / EC-340 and 2.5 A to 3 A for EC -330 ), it signals that the battery is 100% charged. In this “Float or Maintenance Charging Stage”, the charger outputs a constant voltage of 13.5 V for 12 V system and 27 V for 24 V system. This helps in maintaining

100% capacity of the battery and also compensates for self-discharge. The battery can remain connected in this stage indefinitely without the risk of overcharging or excessive loss of electrolyte. 3 stage charging is recommended for charging stand-alone unloaded batteries (there is no load connected to the battery when it is being charged). If a load is also connected simultaneously, a part of the charger’s output current will be diverted to this load. Thus, the charger may remain locked in the “Boost or Absorption Mode” if the current drawn by the load is more than the preset value of threshold current Determining change over between the Boost and Float Stages. This will lead to overcharging and loss of electrolyte. For charging a battery when a load is also connected simultaneously, the “Boost or Absorption Stage” is required to be disabled. Select “Battery with Load” using the Dip switch. See details under “Powering Other DC Loads” at page 10. The charger has the following protections: Short Circuit Shut Down In case of a short circuit on the output side, the charger will shut down. The red LED will switch off. The charger will automatically recover once the short circuit condition is removed. Over load Current Limiting The current drawn by the load is automatically limited to a maximum of 15 A for EC-315 / EC-340 and 30 A for EC-330. If the load tries to draw a higher current than these limits, the output voltage of the unit will start to drop. The unit will automatically recover when the overload condition is removed. Reverse Battery Connection Cut Off The output is internally fused on the DC side. In case, the polarity of the battery connection is reversed, the fuse(s) will blow . The red LED will switch off. The fuse(s) will be required to be replaced for the unit to function again. Thermal Overload Shutdown CAUTION : Keep the charger in a well ventilated, cool and open area. Do not block the vent holes on the sides or the discharge openings of the cooling fan. EC-315 is cooled by convection and does not have any thermal overload shut down. EC-330 and BA-340 are cooled by convection and in addition, have a temperature controlled fan for forced air cooling. Two temperature sensors mounted on the power transformer control the switching of the fan and over temperature shut down. The fan will be switched on by the first temperature sensor when the power transformer reaches 70 degrees C. HENCE, AT LOWER LOADS, THE FAN MAY NOT CUT IN AND WILL BE OFF. THIS IS NORMAL. In case the fan fails or if the cooling is not adequate, the second temperature sensor will shut down the unit if the power transformer reaches 100 degrees C. The red LED will switch off. The unit will automatically recover on removal of thermal overload condition.

Selecting AC input voltage If you want to change the existing AC input voltage to be 115VAC / 60Hz or 230VAC / 50Hz, please adjust the internal setting as follows: 1. Remove the 4 screws on the ammeter side of the top cover 2. Gently slide the top cover out by 2 to 3 inches. ( Caution ! The top cover will be

restrained from fully sliding out by the wires connecting the ammeter, LED and the fan )

3. Locate the jumper wire with a quick female disconnect. In the pre-set condition, it is connected to the male vertical pin. Pull this female disconnected upwards to disconnect from position. Connect this to the male vertical pin marked “115 V” or “230V” you required.

4. Replace the fuse with the fuse recommended for operation (See fuse rating at page 12)

5. Replace the AC plug of the power cord with a suitable 3 pin grounded plug to mate with the outlet. ( Caution !! The new plug should have 3 poles i.e. Line ( L ) , Neutral ( N ) and Earth ground. Color code for the power cord conductors is : Line ( L ) - Black , Neutral ( N ) – White and Earth ground – Green )

Selecting the Type of Battery and Charging Stages The Float Voltage and Boost Voltage (Also called Absorption or Overcharge Voltage ) of different types of Lead Acid Batteries are different. Also, when a charger is used to charge a battery and simultaneously supply a load , the Boost Stage is required to be disabled to prevent overcharging of the battery . A Dip Switch is provided on top of the output terminals for selecting the battery type and for disabling the Boost Stage when charging loaded batteries. The following selections can be made with the help of the Dip Switch. CAUTION ! (Do not change the Dip Switch setting when the charger is operating. Always change the Dip Switch setting when the charger is off , i.e. after disconnecting the charger from the AC input power ). NOTE : The voltages are for a temperature of 80 Degrees F DIP SWITCH SETTINGS - EC-315 / EC-330 S1 S2 Float Boost Battery Type Charging Stages OFF * ON * 13.5 V * 14.4 V * Flooded / AGM * 3 Stages (Stages 1, 2, 3) ON OFF 13.5 V 14.0 V Gel Cell 3 Stages (Stages 1,2,3) OFF OFF 13.5 V Disabled Battery with load 2 Stages (Stages 1, 3) ON ON Caution !!!

CAUTION ! PLEASE ENSURE THAT POSITION NO 4 OF THE DIP SWITCH ( S1-ON AND S2-ON ) IS NEVER SELECTED Connecting the batteries or other DC loads The output has a common Negative ( - ) terminal and 3 Positive terminals for connection of 3 banks of batteries. Each Positive connector has it’s own internal isolating diode which works as a battery isolator. If more than one bank of batteries is connected, these will be charged at the same time ( The maximum charging current of 15 A of EC-315 / EC-340 and 30 A of EC-330 will be shared among the connected banks of the batteries depending upon their discharged states ) as long as the AC power is available to the charger. In case the AC power fails or if there is no output from the charger , the isolating diodes will prevent charging / discharging among the batteries connected to the banks. CAUTION ! When a bank consisting of more than one battery in parallel is to be charged , make sure that their negatives are connected to the common negative terminal of the charger and their positives are connected to the same positive terminal of the charger. For example, when charging a bank consisting of 3 batteries connected in parallel, their 3 negative terminals should be connected to the common negative terminal of the charger and all their 3 positive terminals should be connected to the same ( one of the 3 ) positive terminals of the charger. Alternatively, the negative terminals of the 3 batteries should first be shorted and then connected to the common negative terminal of the charger and similarly, the 3 positive terminals of the battery should first be shorted and then connected to one of the 3 positive terminals of the charger. When connecting a single battery or other DC load, it can be connected to the common negative and any one of the 3 positive terminals.

OPERATION

When the charger is switched on, the red LED lights up indicating that output voltage is available. When the batteries are being charged or when the charger is supplying other DC load, the current Fed by the charger will be indicated by the ammeter. When the batteries are discharged, they will draw charging current proportional to their discharged condition (up to a maximum current rating of the charger) and this current draw will be shown by the ammeter. When the batteries are fully charged, they will draw very low current ( may not be registered by the ammeter ) to compensate for their self discharge. Charging a Battery Installed in a Vehicle Follow these steps when the battery is installed in a vehicle. A spark near a battery may cause battery explosion. For safety and to reduce the risk of spark near the battery : 1. Position AC and DC cords to reduce risk of damage by hood, door or moving engine parts 2. Stay clear of fan blades, belts, pulleys and other parts that can cause injury to persons 3. Check the polarity of the battery posts. A positive ( Pos, P, + ) battery post usually has a

larger diameter than a Negative ( Neg, N, - ) post 4. Determine which post of the battery is grounded (Connected) to the chassis (Engine

Block). If the negative post is grounded to the Engine Block ( As in most vehicles ), see sub paragraph 5. If the positive post is grounded, see sub paragraph 6

5. For a negative grounded vehicle, connect the positive (red) DC cable from the charger to the positive of the battery post. Connect the negative (black) DC cable from the charger to a section of heavy gauge metal part of the frame or engine block which is away from battery. Do not connect to carburetor, fuel lines or sheet metal body parts.

6. For a positive grounded vehicle, connect the negative (black) DC cable from the charger to the negative of the battery post. Connect the positive (red) DC cable from the charger to a section of heavy gauge metal part of the frame or engine block which is away from battery. Do not connect to carburetor, fuel lines or sheet metal body parts.

7. Connect the charger AC power cord to the AC outlet 8. When disconnecting the charger, turn switches to off, disconnect AC power cord, remove

connection from the vehicle chassis and then remove connection from the battery terminal

Charging a Battery outside the Vehicle Follow these steps when the battery is outside the vehicle. A spark near the battery May cause battery explosion. For safety and to reduce risk of spark near the battery, connect the charger as follows : 1. Check the polarity of the battery posts. A positive ( Pos, P, + ) battery post usually has a

larger diameter than a Negative ( Neg, N, - ) post 2. Attach a piece of at least 3” of AWG #6 insulated battery cable to the negative battery post 3. Connect the positive (red) DC cable from the charger to the positive battery post 4. Position yourself and the free end of the piece of cable attached to the negative post as far

away from the battery as possible and then connect the negative (black) DC cable from the charger to the free end of the piece of cable attached to the negative battery post

5. Do not face the battery when making the final connection 6. Connect the charger AC power cord to the AC outlet 7. When disconnecting the charger, always do so in reverse sequence of connecting procedure

and break the first connection while standing as far away from the battery as practical

- 10 -

CAUTION ! When charging more than one bank of batteries at the same time using 3 Stage Charging, ensure that the batteries in the banks are in a similar discharged condition. If one bank is completely discharged and another is almost fully charged, the bank that is fully charged will be subjected to over charge condition during the time when the charger remains in Boost Stage for charging the completely discharged bank. Powering other DC Loads The charger can be used as a power supply or as a DC UPS . For both these applications, first set the Dip Switch to “Battery with load”. ( See under “ Selecting the Type of Battery and Charging Stages” on page 7 ). To use as a power supply, first switch off the DC load. Connect the DC load between the common negative terminal and one of the three positive terminals. Ensure that the maximum current drawn by the DC load is below the maximum current rating of the charger. Switch on the charger and then the DC load. In a DC UPS ( Un-interruptible Power Supply ) , the charger simultaneously powers the DC load as well as the battery. As long as the AC power to the charger is available and The charger is working normally, the charger will supply the DC load as well as charge / float the battery. In case the AC power fails or if the charger stops working, the battery will automatically power the DC load. As soon as the AC power to the charger is restored , the DC load will once again be fed by the charger and at the same time the battery will be recharged. CAUTION! Please ensure that the sum of the current drawn by the DC load and the current desired for charging the battery is less than the maximum current capacity of the charger. To use as a DC UPS, first switch off the DC load and connect it to the battery. Now connect the battery as explained above under “Charging a Battery outside the Vehicle” on page 9. Switch on the charger and then switch on the DC load .
