Notice:
If the UPS is supplied by AC generator, please follow the requirements below
：
1
. Start up the AC generator 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 the UPS is supplied with AC mains without being 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 comes directly
from the AC mains input; and meanwhile the charger charges the
battery. When in Bypass mode, the bypass indicator on the LCD
panel shines green, as shown in Fig. 3-2. Please note: In the event
of bypass power failure or bypass voltage outside tolerances when
the UPS is in Bypass mode, the UPS is unable to supply the load.
