5) Turn on the parallel system in Battery mode:
a) Turn on the battery disconnect (available on long-range models only) and the external output
disconnect of each UPS .
b) Turn on any UPS. A few seconds later, the UPS will enter battery mode.
c) Turn on the next UPS in sequence until all UPSs enter Battery mode and add them to a parallel
system. Now the parallel system is completed.
If you would like to obtain more information regarding parallel operation, please contact your supplier or
service center for detailed parallel operation instructions.
2. Add new units into the parallel system
1) You cannot add new units into a parallel system while the whole system is running.
You need to disconnect the load and shut down the system.
2) Make sure all UPSs are parallel models, and follow the wiring reference in sections 2-4 .
3) Install a new parallel system as per sections 3-5.
3 . Remove the unit from the parallel system
There are two methods for removing units from parallel systems:
First method:
1) Touch "CONTROLè" "Turn Off UPS" and select "Yes" to turn off UPS. Then, the UPS will enter Bypass
mode or "No Output Mode" mode with no output.
2) Turn off the output breaker of this unit, and then turn off the input breaker of this unit.
3) Turn off the battery breaker (for long-range models) and disconnect the parallel current and
share wires. And then disconnect the unit from the parallel system.
Second method:
1) If the bypass is abnormal, you cannot remove the UPS without interruption . You have to cut the
load and close down the system .
2) Make sure the bypass setting is enabled d on each UPS and then shut down the system . All UPSs
will switch to Bypass mode . Remove all maintenance bypass covers and set the maintenance
switch from the "UPS" position to the "BPS". Turn off all input breakers and battery breakers in a
parallel system.
3) Turn off the output breaker and disconnect the parallel cable and share the UPS current cable you
want to remove. Now, you can disconnect the UPS from the parallel system.
4) Turn on the input breaker of the remaining UPS and the system will switch to Bypass mode. Set the
maintenance switch from "BPS" to "UPS position and reinstall the maintenance bypass cover.
5) Turn on the rest of the UPS according to the previous section .
Warning: (Only for parallel systems )
●
Before turning on the parallel system to activate the inverter, make sure that all the maintenance
switches of the unit are in the same position.
●
When the parallel system is turned on, please do not operate any unit maintenance switch.
●
Parallel systems do NOT support ECO mode . Therefore, please DO NOT "Enable" ECO mode in any
unit.
