Troubleshooting guide
Charge the UPS for at least 7 hours before storing the unit. Cover the UPS, and place it upright in a cool, dry location.
During storage, recharge the battery in accordance with the following table:
The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified maintenance
personnel.
Even after the unit is disconnected from the mains, components inside the UPS system are still connected to
the battery packs which are potentially dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no current
is present and no hazardous voltage exists in the terminals of high capability capacitor such as BUS-capacitors.
Servicing of batteries should be performed or supervised by personnel with knowledge of batteries and the
required precautions. Keep unauthorized personnel away from batteries.

When the parallel system is used,
make sure that the parallel

number is correct after turning on
input breakers one at a time. If all

fine to turn on the UPS after disabling
the warning message by pressing the
‘UP’ and ‘DOWN’ buttons at the same
time. Otherwise, do NOT turn on the
UPS and contact your dealer
for assistance.
For single UPS, since there is no
communication cable and parallel
output cable connection, simply
ignore this warning message by
pressing the ‘UP’ and ‘DOWN’ button
to disable and turning on UPS for
continuous operation.
Parallel communication
cable is loose or incorrect
parallel operation.
Check fans and notify dealer.
