When the Charger is switched oN, Green LeD “Charger” (7, fig 3.1) is lighted.
Please note that the Charger is powered from the Utility AC Power. Hence, the charger
will switch off when Utility AC Power fails even if the charger oN/off Switch is in oN
Condition.
operation as Backup ac power Source - Switching on
1. Make sure that the maximum single / combined load is less than 1500W. Please refer to
Sizing Chart at Table 5.1 for guidance.
2. Switch off the Inverter and the Charger.
3. Switch off the load(s).
4. Connect the load(s) to the AC outlet(s) of the inverter (1, fig 3.1) .
5. Switch oN the Inverter. Green LeD “Inverter” (8, fig 3.1) will be lighted.
6. Wait for a few minutes and then Switch oN the load(s). If more than one load is used,
switch oN one by one so that starting surges are staggered to prevent overload shut down
7. Under normal operation, the load(s) will be powered from the inverter. refer to Trouble-
shooting Guide in case abnormal operation is observed.
8. Plug the NeMA5-15P plug of the AC Input Cord (10b, fig 3.1) into 120 VAC, 15A/ 20A GfCI
protected AC outlet. The Transfer relay will operate and transfer the load to the Utility AC.
Inverter will be in standby condition.
9. Switch oN the battery Charger. Green LeD “Charger” (7, fig 3.1) will be lighted. The
battery will start getting charged as described under “2 Stage Charging” in
Section 2, page 7.
10. If the Utility AC power fails, the Transfer relay will transfer the load(s) to the Inverter in
around 2 to 3 sec. battery Charger will switch off. The battery will start discharging at
current = Power of AC load(s) in Watts ÷ 10.
