Central Battery Systems INV 220V Series
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.
Remark : Central Battery Systems by Inverter 220V Series has 2 function modes of operation.
1. MAINTAINED (Providing lighting constantly throughout the period when the AC line lights are in the
normal status and when the AC Line lights are o .)
2. NON–MAINTAINED (Providing emergency lighting only when the AC line lights are o .)

- Page 4 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.

Page 10: Maintenance
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. - Page 11 Note : Please read the manual carefully before installation and operation to understand how to properly operate the unit.
