Chapter 3 Operation
3.1 Operating Mode
3.1.1 Normal Mode
When the input Utility voltage and the load are within specifications, the load is
supplied by inverter, which draws power from rectifier; meanwhile, the charger
float-charges or equalize-charges the battery. When in Normal mode, the Utility
indicator and inverter indicator on the LCD panel be green in colour ,as shown in Fig.
3-1.

Note
If the UPS is power by generator set , please follow the requirements below:
1. Start up the generator set first without switching on the loads, connect the UPS to the generator,
then switch on the loads one by one till the generator operates stably (to ensure reliable operation of
the generator, it is recommended that the UPS load be less than 30% of generator capacity).
2. It is recommended that the
generator capacity be 1.5~2 times of UPS rated capacity.
3.1.2 Bypass Mode
When utility is present and UPS is not turned on , or in the event of overload or other
faults after the UPS is turned on, the load is supplied by Bypass AC source, which
feeds directly from the Utility input; and meanwhile the charger will charge the battery.
When in Bypass mode, the bypass indicator on the LCD panel turns green, as shown
in Fig. 3-2. Please note: In the event of bypass power failure or bypass voltage falling
outside tolerance when the UPS is in Bypass mode, the UPS will cease to supply
electricity to the load .
