Check the output voltage of each UPS system. The phase deviation
between each UPS system should be less than 5V. If the phase
deviation is within the acceptable range, switch on the output

9-9 Shutdown Procedure (Parallel UPS)

Warning: The UPS system shutdown procedure will eliminate the AC power output for all loads. Before shutdown, confirm that all loads
are turned off or place the UPS systems in manual bypass mode to keep loads powered by the bypass (reserve) power source.

If the other UPS system can support the connected equipment
loads alone, the UPS system that was turned off will shut down its
inverter and its LCD screen will read "LOAD NOT POWERED".
The other UPS system's LCD screen will read "ONLINE MODE".
If the total connected equipment load is too large to be handled
by a single UPS system, both UPS systems will shut down their
inverters and switch to bypass mode, and their LCD screens will
read "ON AUTO BYPASS".
For the UPS system you wish to shut down, switch off the main
