How to join a new UPS to a parallel system:
1) First the parallel system must be installed one main maintenance bypass
switch.
2) Regulate the output voltage of the new UPS separately: check if the output
voltage difference between the new UPS and the parallel system is less than
0.5V.
3) Ensure the bypass of the parallel system is normal and the bypass setting is
"enable", remove the cover plate of maintenance bypass switch on the rear
panel of each UPS, the UPS system would transfer to bypass automatically.
Set the own maintenance bypass switch of each UPS from "UPS" to "BPS".

cover plate back again. Press the button
start to turn on, after turning on, the UPS should work parallel in the Line
mode.
How to remove a single UPS from a parallel system:
1) First the parallel system must be installed one main maintenance bypass
switch.
2) Ensure the bypass of the parallel system is normal and the bypass setting is
"enable", remove the cover plate of maintenance bypass switch on the rear
panel of each UPS, the UPS system would transfer to bypass automatically.
Set the own maintenance bypass switch of each UPS from "UPS" to "BPS".
