Before switching on external battery cabinet switch, the bus voltage should be higher than the rated
DC input voltage.
After finishing starting rectifier, ensure the float charging/ equalized charging voltage setting match
with practical battery parameters.
Step 4
Start inverter system.
When power on, press and hold ON combination button, the
green indicator is on. 30s later,
finish starting inverter. Check whether the output voltage is the required voltage value.
Step 5
Switch on output switch.

5.2.2 Start Load
Step 1
Observe indicators on the panel to judge working status of UPS. If indicator shows UPS works in the
mains inverting status or battery inverting status(refers to
), it can supply
power for load.
Step 2
If UPS has worked without load for about 10 minutes, start load with the sequence that is "high
power device
→
small power device".
Some devices(e.g. motor type load) generate large current when startup, and may lead to overload
protection (or on bypass). It is better to start them first.

5.2.3 Close UPS
Before closing UPS, close load first and keep UPS working without load for 10 minutes to exhaust
heat.
Step 1
Turn off inverter.
