4. Removing one unit from the parallel system
There are two methods that can be used to remove one UPS from the parallel system:
First method:
1) Press the
OFF
button twice for about 0.5 second each. The UPS will enter into bypass mode without output.
2) After turning off the output breaker, do the same with the input breaker of the UPS.
3) After the UPS shuts down, turn off the battery breaker. Then remove the parallel cable and share current cable. You can now
remove the unit out from the parallel system.
Second method:
1) If the bypass is abnormal, the UPS cannot be removed without interruption. You must first power down the load and complete
ly shut down the UPS system.
2) Enable the Bypass setting in each UPS and then power off the running UPS. All UPS units in the parallel system will transfer to
Bypass mode. Remove all maintenance bypass covers and change the maintenance switches from
UPS
to
BPS
. Next, turn off
input breakers and battery breakers.
3) Remove the desired UPS.
4) Turn on the input breaker of the remaining UPS units and the system will transfer to Bypass mode.
5) Set the maintenance switches from
BPS
to
UPS
and replace the maintenance bypass covers. Turn on the remaining UPS units
and finish the parallel system connections.
Warning:
(parallel system only)
• Before turning on the parallel system to activate the inverter, make sure that every maintenance switch on the UPS is in the same
position.
• When the parallel system is turned on to operate through the inverter, do not change the maintenance switch of any unit.

Parameter 1:
it is used for the different configu-
ration options. There are 16 programs to set up.
Refer to the table below.
Parameter 2 and parameter 3:
they represent
the setting options or values of each program.
Parameter 1
Parameter 2
Parameter 3
List of the programs for parameter 1:
*Y means that this program can be set in this mode.
Note:
All parameter settings will be saved only when UPS shuts down normally with internal or external battery connection.
(Normal UPS shutdown means turning off input breaker in bypass/no output mode).
3-7. UPS parameter settings
Three parameters need to be configured in order to set up the UPS. Refer to following diagram:
