3. Remove units from the parallel system
Check that Mains and Bypass Supplies are both healthy
COMPLETE THE FOLLOWING ON UNIT TO BE REMOVED:
1)
Touch “CONTROL”
➔
“ Exit Parallel ” and select “Yes” to tu rn of the UPS. If the system has available
redundancy the UPS will disconnect its output and the other UPS units will continue to feed the load.
If there is no redundancy within the UPS units, the load will transfer to bypass.
2)
Turn off the output breaker of this unit, and then turn off the input and bypass breaker of this unit.
3)
After UPS shuts down, you can turn off the battery breaker and remove the parallel and share
current cables. Then remove the unit from the parallel system.
NOTE1 : IF “ON/OFF UPS” is selected all UPS will transfer to bypass.
NOTE2: If the bypass is abnormal and there is no redundancy available removing a UPS from parallel
could cause disruption to the load.
NOTE3: Make sure the bypass setting is enabled in each UPS
Warning: (Only for the parallel system)
● Before turning on the parallel system to activate inverter, make sure that all units maintenance
bypass switches are in the same position.
● When parallel system is turned on, please do not operate the maintenance switch of any unit if the
system is operating in capacity and not redundancy.
● Please Do NOT enable the ECO mode in parallel system.
