Inverter Failure 

 

Output load short circuit when supplied via inverter 

If the output load is short-circuited while supplied via inverter, the UPS will shut 
down the inverter automatically and cut the supply to the loads. The Fault LED 
will shine, and the buzzer will beep continuously. The UPS will not switch on 
automatically after the short-circuit condition is eliminated. The UPS must be 
restarted manually. (Refer to section 4.3.1.1. ‘Start Up in Normal AC Mode’.)

5.6. 

Overheating 

 

If the UPS overheats when the utility is normal it will switch into bypass mode. 
The UPS will switch back to inverter mode when the overheating is eliminated. 
If overheating occurs when the utility is abnormal the buzzer will beep 
continuously and the Fault LED 

  will shine. The UPS will cut off supply to 

the loads. 

 

5.7. 

Inverter Current or Voltage Out of Tolerance 

 

If the UPS inverter delivers over-current or out-of-tolerance voltage to its 
outlets then the UPS is out of order. The UPS will switch into bypass mode 
when the utility is normal. The Utility 

 LED, Bypass 

 

LED, and Fault 

 

LED will shine. 

 

If these two fault conditions occur when the utility is abnormal the UPS will cut 
off the supply to its outlets, and the Fault 

  LED will shine.

Troubleshooting 

 

If the UPS malfunctions during operation please check that all lines are 

connected properly and that the utility specifications are correct. Then check the 
table below for solutions. Should the problem persist please contact your local 
dealer for assistance. 
 

Situation Check 

Items 

Solution 

1. Er05,Er24 
 
 
 
 
 
 
 
 

1. Check for proper battery 

connection. Measure battery 
voltage to ensure that batteries 
are charged and healthy. 
Recharge batteries for 8 hours if 
necessary. Simulate utility outage 
to verify that UPS is able to 
provide DC backup. Otherwise 
consult your local dealer right 
away. 

2. Overload 
 
 
 
 
 

2. Disconnect some non-critical 

loads from the UPS output until 
the overload ceases. Check if 
there is any short circuit between 
cables due to broken cable 
insulation. Replace the cables if 
necessary. 

3. Er11 (UPS Over 

Temperature) 

 
 
 
 
 

3. Remove any objects obstructing 

the ventilation louvers. Verify that 
the cooling fans are working 
properly. Contact your local 
dealer to replace the fans if 
necessary. 

4. Site wiring/Ground fault 

 

 
 
 

4. Check if the “L” and “N” phases of 

the utility AC source have been 
wrongly wired or if the Ground-
Neutral voltage exceeds the 
limits. 

5. Er14 (Fans out of order)
 
 
 
 

5. Verify that the ventilating fans are 

functioning properly. Do not 
attempt to replace the fans 
yourself. Contact your local dealer 
for replacement. 

Fault

Read the error code (see 
next page) displayed by 
the combination of LEDs,
and verify the fault as 
follows.
