Appendix A Troubleshooting
PROBLEM POSSIBLE
CAUSE
Solutions
Input power source mistake Check out the power source
Time of pressing the button
is too short
Keep pressing the “ON/TEST”
button over 2 seconds
z
UPS can't operate
after pressing
“ON/TEST” switch
z
No lights on, no
warning sounds
Output short circuit or
overload on UPS
Turn off UPS, take off all load
to make sure there are no
problems on it or any internal
short circuit. Keep pressing the
ON button over 2 seconds
No power source input
Check the input power source
Indicates no utility,
and it warns every
several seconds
Fuse or Fuse or Circuit
breaker open.
Fuse or Circuit breaker open.
Buzzer keeps
beeping
Overload
Take off some load
Fuse or Circuit breaker
open.
Press on the circuit or replace
the fuse (spare in inlet).
Utility Indicating light
is shining
The voltage of utility is
exceeding UPS input range
Save the digital data and
shutdown the applying
program to make sure utility is
within UPS range
z
Batteries haven't been
charged
z
UPS
overload
z
Batteries are aged and
can't be charged fully
Keep UPS "ON" for over 6
hours to recharge the
batteries. Check out the
loading and take off any
non-crucial load equipment
Available time of the
batteries is too short.
The charger is out of order
Contact the dealer or service
center for help
The battery’s light is
flashing when the
power of UPS is
supplied by utility.
The voltage of batteries is
too low or the batteries
haven't been connected
Check out the batteries part of
UPS, make sure they are well
connected. If there is any
damage on battery packs,
replace new ones ASAP
