USER MANUAL For Central Battery Systems – INV220V Series

Part 1

Overview Central Battery Systems

1.1 Features

Central Battery Systems by Inverter 220V is used to detect any abnormalities of the main power distribution system. In case of error or emergency, the unit will convert the battery voltage stored in the chemical form into the electric power and supply it to the inverter where the DC voltage from the battery will be converted into the AC voltage at 220VAC 50Hz to turn on the emergency light. On the other hand, when the main power distribution system resumes its normal operation, the unit will stop supplying the backup power and start recharging the battery for later use in case of another error or for the emergency light test.

Central Battery Systems by Inverter 220V Series has 2 function modes of

operation.

MAINTAINED (Providing lighting constantly throughout the period when the AC line lights are in the normal status and when the AC Line lights are off.)
NON–MAINTAINED (Providing emergency lighting only when the AC line lights are off.)

Installation and Operation

2.1 Battery Connection

Since the inverter operates at a voltage of 24 Volts and 48 Volts, for maximum efficiency the batteries are connected together to increase its voltage from 12 Volts to 24 and 48 Volts as shown in the diagram connecting the battery with the battery in the box connecting the positive (+) and negative (-) cables correctly.

2 Batteries in Series (24V)

2 Parallel Sets of Batteries in Series (24V)

4 Batteries in Series (48V)

2 Parallel Sets of Batteries in Series (48V)

Warning

Set all the breakers to Off prior to connecting the batteries.
Connect the cables to the correct battery terminal following the wiring diagram.
Do not short-circuit the battery terminals.
Check the Voltage of the battery after the connection to make sure if it is the desired 24 Volts or 48 Volts.

2.2 Steps for Connecting the Input and Output

1.) Test the readiness of the output load, for example, check for any short- circuits or if the total wattage exceeds the acceptable load. (Caution: The Output Line and Neutral circuit should be independent from other circuits otherwise damage could occur to the inverter.)

2.) When connecting to the Load Output in the circuit box there will be 2 outputs to choose from, which are

2.1 Output Maintained. This connection will provide a constant 220Vac 50Hz current. This is suitable for uses that requires a constant current both during normal conditions and during power outages, for example, providing power for emergency exit signs without a built-in battery or lights that need to be constantly on such as lights installed in fire escapes or in parking lots.

2.2 Output Non-Maintained. This connection will not provide a 220Vac 50Hz during normal conditions. The connection will only provide power during power outages. This connection is suitable for things such as emergency illumination lamps.

Caution: For the correct connection the Line should be connected into L, Neutral should be connected to N and Ground should be connected to PE The cables should be connected securely and no foreign objects should be in the circuit box that could potentially cause a short-circuit.

3.) Connect the Input cables to the Input 220VAC terminal inside the red frame inside the circuit box. The Line cable should be connected to the L terminal, the Neutral cable to the N terminal and the Ground cable to the PE terminal. The cables should be connected securely and no foreign objects should be in the circuit box that could potentially cause a short-circuit.

2.3 Device Initialization

1.) Turn on the Circuit Breaker BATT and the Circuit Breaker AC INPUT 220VAC (as indicated by the red frame). The device will begin charging the battery and enter a ready-to-use state. The front of the device will display the following status:

operation

2.) Set the Breaker AC.Input 220VAC to Off, the inverter will start operation as the same time set the Breaker MAINTAINED, NON-MAINTAINED to On (shown in the red marking), the unit should now be providing power to the load.

3.) Test to see if the overall current level and load stability is at a normal level.
4.) Set the Breaker AC.Input to ON (shown in the red marking), after the unit should stop using the inverter and use the main power supply to provide power instead.

2.4 Testing the Unit’s Operability

1.) To test the unit, the user can set the Circuit Breaker AC Input 220VAC to OFF (shown in the red markings), the unit should start providing backup power to the emergency lights immediately.

2.) To stop the test, the user can set the Circuit Breaker AC Input 220VAC back to ON. The inverter should stop operating and the unit should return to standby mode.

3.) The unit has a built-in self-testing system that will perform 30 minutes self-tests every 30 days. This self-test system should start working once a current from AC. Input is provided to the unit.

4.) If during the self-tests the battery is found to be faulty and cannot hold a charge or less charge that normal the unit will show a “Battery Fail” warning.

Note: You can reset the alert by turning off and on the Circuit Breaker AC INPUT 220VAC and Circuit Breaker BATT.

5.) In the event that there is an abnormality in the battery charging system, such as over-charging voltage, inability to charge, and charging for more than 24 hours, the unit will display the “Charging Fail” status.

Maintenance

3.1 Device Maintenance

1.) Keep ventilation fan of the unit clean.

2.) The unit has an Automatic testing system, automatically enabling 30 minute test every 30 days. If your unit does not have a self-test system you should manually test the unit once a month for 30 minutes to make sure the unit is fully operational and to help extend the life of the battery.
