Other functions
a) Test Function:
Test the function of the UPS system either by pressing the On-Switch “I” or disconnecting the
input of the UPS system from the mains supply.
b) Audible Alarm Mute Function:
If the alarm is too annoying in battery mode, you can press “I” button continuously for more than
1 second to clear it. Moreover, the alarm will be enabled when the battery is low to remind you
to shutdown the load soon.

. The parallel system Maintenance
This parallel system comprises two or more UPS units operating in parallel to feed a common
load bus., if you want to add single unit to parallel system, please refer to the following
instructions of “Add a new unit to the parallel system”.
Add a new unit to the parallel system:
a) Prepare input & output cables, switch and combine cables.
b) The input and output switches of the new unit should be turned off, remove the connection
between JP1 and JP2.
c) Turn off the UPS system, and transfer all UPSs to bypass mode:, switch all UPSs’
maintenance switches from ‘UPS’ to ‘BPS’ and then turn off all UPSs’ input switches.
d) If the new UPS system is configured for single module mode, remove the connection
between JP1 and JP2.
e) Take apart the board of parallel ports, insert one end of combine line into parallel card’s slot
and screw down its pin; and then lock up the board of parallel ports over again; at the same
time, take apart the maintain board of new UPS.
f) Turn on the battery switch of new UPS and line input connection switch outside; measure
voltage difference between output live wire of new UPS and parallel system. If the voltage
difference is less than 1V, please close output live wire’s witch of new UPS.
g) Take apart the board of parallel ports when UPS has switched to bypass mode, insert the
other end of combine line into parallel card’s slot and screw down its pin; and then lock up
the board of parallel ports over again.
h) Close line input switch of all UPS (include new UPS) in the parallel system; lock up maintain
board, unless all UPS turn to bypass mode; press the open key in turn, observe whether
the display state of every UPS is normal; at the same time, observe whether all UPS all
together enter inverter mode or not; and measure the voltage difference of every UPS
ports’ JP2.
i) Turn off all UPS, take apart maintain board of all UPS unless they all have switched to
bypass mode. Turn all the maintain switches from “BPS” to “UPS” and lock up every
maintain board.
