2.2.2 Series Hot-standby
Connect the bypass input of UPS2 to the output of UPS1 instead of mains, it constitutes series
hot-standby working mode.
When UPS2 fault, it will turn to bypass mode automatically. At this time, the UPS1 supply power for
load, the load stay on UPS1 inverting protection status to ensure safety work. If the UPS2 stay on
bypass mode, and the UPS1 fault at the same time, the mains will supply for load directly.

2.3 Work Mode
The UPS has 4 working modes: mains mode, battery mode, bypass mode and maintenance bypass
mode.

2 Overview
Three-Phase UPS (10kVA-160kVA) Series
User Manual

Mains mode
When mains normal, the rectifier will convert the AC power into DC power to charge battery and
supply power for inverter to provide pure AC for load.
Battery mode
When mains abnormal or rectifier stops working, the batteries connected with DC.BUS will supply
power for inverter and the AC output will not interrupt.
Bypass mode
When the inverter abnormal (such as over-temperature, short circuit, output voltage abnormal or
overload and exceed the range that the inverter can withstand), the inverter will shut down
automatically to avoid damage. If the mains still normal at this moment, bypass power will instead of
mains power to supply power for load by static switch.
Maintenance bypass mode
When the UPS needs to be maintained or the battery needs to be replaced and at the same time, the
power supply for load cannot be interrupted, shut down the UPS firstly, then switch on the
maintenance bypass switch and then switch off the switches of mains, bypass, output and external
battery cabinet. During switching to maintenance bypass manually, AC power supplies power for
load through maintenance bypass switch. Meanwhile, there is no electricity inside UPS (except N),
and maintainer can carry out the maintenance safely.
