PH 9283 - PH 9284 .
3) Turn on the parallel system without utility power supply (in Battery mode).
1) Turn on the battery breaker (only available in long-run model) and output breaker
of each UPS.
NOTE: It is not allowed to share one battery pack for long-run UPS’s in parallel system. Each UPS
should be connected to its own battery pack.
2) Turn on any UPS. A few seconds later, the UPS will enter to battery mode. Then
turn on another UPS. A few seconds later, the UPS will enter to battery mode and
add to the parallel system.
4) If you have the third UPS, follow the same procedure.
4. Add one new unit into the parallel system
1) You cannot add one new unit into the parallel system when the whole system is
running. You must cut off the load and shutdown the system.
2) Make sure all the UPS are parallel models and follow the wiring in section 2.3.
3) Install the new parallel system refers to the previous section.
5. Remove one unit from the parallel system
There are two methods to remove one unit from the parallel system:
Method 1:
1) Press the “OFF” key twice and each time should last for more than 0.5s. Then, the UPS
will enter into bypass mode or no output mode without output.
2) Turn off the output breaker of this unit, and then turn off the input breaker of this unit.
3) After it shuts down, you can turn off the battery breaker (for long-run model). Remove the
parallel cable and share current cable. Then, remove the unit from the parallel system.
Method 2:
1) If the bypass is abnormal, you cannot remove the UPS without interruption. You must cut
off load and shut down the system.
2) Make sure that bypass setting is enabled in each UPS and then turn off the running
system. All UPSs will transfer to bypass mode. Remove all the maintenance bypass covers
and set the maintenance switches from “UPS” to “BPS”. Turn off all the input breakers and
battery breakers in parallel system.
3) Turn off the output breaker and remove the parallel cable and share current cable from
the UPSs that you want to remove. Then, remove UPSs from the parallel system.
4) Turn on the input breaker of the remaining UPSs and the system will transfer to bypass
mode. Set the maintenance switches from “BPS” to “UPS and put the maintenance bypass
covers back.
5) Turn on the remaining UPSs by following section 3.5.(1)
WARNINGS : 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 to work through inverter,
please do not operate the maintenance switch of any unit.
