Put all the equipments on Bypass and, next, remove the l.
cover of the maintenance bypass of each UPS and move
the maintenance switch from «BPS» to «UPS» and screw
the cover back.
Start up the UPSs on Line mode to operate in parallel op- m.
erating.
i
If the UPS is wrong with the above procedure,
make the maintenance according to the steps to
remove one UPS.
Procedure to remove one UPS. 3.
In case is needed to remove one UPS from the parallel a.
system, which is running normal, press the OFF Button
twice consecutively and that UPS will shutdown its output
immediately.
Turn OFF the circuit breakers of input, mains, output and b.
battery of the UPS to remove.
Press the OFF button of the rest of UPSs. Once all have c.
transferred to Bypass mode, remove the maintenance by-
pass cover of each UPS, move the maintenance switch
from «UPS» to «BPS» and turn OFF the input circuit
breaker.
Once removed the UPS, the bridge between JP1 and JP2 d.
of the UPS terminal strip has to be done in case only one
UPS will remain in the system.
Once all the LCD panels are shutdown, remove the cover e.
from the parallel port located in the UPS to remove, ex-
tract parallel cable and screw the cover back.
Turn OFF all the input circuit breakers of the rest UPSs. Once f.
all UPSs have transferred to Bypass mode, move the main-
tenance switch from «BPS» to «UPS» and screw the cover
back. Put all he UPSs on Line mode to run on parallel.
If the removed UPS will be used on single mode, JP1 and g.
JP2 have to be bridged.
Parallel system warnings:
When the system runs on inverter mode, make sure that a.
all the maintenance switches of the UPSs are in the same
position (either on «UPS» or on «BPS»).
Enter into inverter mode before start up the system. The b.
output circuit breaker has to be turned OFF.
Do not touch the maintenance switch meanwhile the c.
system runs on inverter mode.
