Second method:
6) If the bypass is abnormal, you can not remove the UPS without interruption. You must cut off
the load and shut down the system.
7) Make sure the bypass setting is enabled in each UPS and then turn off the system. All UPSs
will transfer to Bypass mode. Remove all the maintenance bypass covers and set the
maintenance switches
from “UPS” to “BPS” position. Turn off all the
input breakers and battery
breakers in parallel system.
8) Turn off the output breaker and remove the parallel cable and share current cable of the UPS
which you want to remove. Now, you can remove the UPS from parallel system.
9) Turn on the input breaker of the remaining UPS and the system will transfer to Bypass mode.
Set the m
aintenance switches from “BPS” to “UPS position and put
the maintenance bypass
covers back on.
10) Turn on the remaining UPS according to the previous section.
Warning: (Only for the parallel system)
●
Before turning on the parallel system to activate inverter, make sure that all
unit’s
maintenance
switch at the same position.
●
When parallel system is turned on, please do not operate the maintenance switch of any unit.
●
The parallel system DOES NOT support ECO mode. Therefore, please DO NOT
“enable”
ECO mode in any unit.
