3. How to join a new UPS:
1) Before joining a new UPS, user need to prepare the input and
output wires, the output breaker, and the parallel cable.
2) Turn off the input and output breakers of the new unit. Connect
the input wires, output wires and battery wires. Remove the
short connection wire between JP1 and JP2 on the terminal
block.
3) Turn off the UPS systems that are running. After all of the
running UPS transfer to the Bypass mode, remove the
maintenance cover board of each UPS and set the
maintenance switch from
“
UPS
”
to
“
BPS
”
, then turn off the input
breaker of each UPS.

need to remove the short connection wire between JP1 and
JP2 on the terminal block.
5) Remove the cover board of the parallel port on the new UPS,
push one end of the parallel cable into the slot of the parallel kit

7) Turn on the battery switch and the input breaker of the new
UPS; measure the difference voltage between the output line
wires of new UPS and the parallel system to check if the
voltage difference between them is less than 1V. If the
difference is less than 1V, close the output breaker. If the
difference is more than 1V, check if the wirings are abnormal.
8) Remove the cover board of the parallel port located on the UPS
which has transferred to the maintenance bypass and push the
