UPS fails to provide 
battery backup or its 
backup time is shorter 
than its intended 
performance. 

If the backup time remains 
unsatisfactory after 8 hours of 
charging please contact your 
local dealer for battery 
replacement.  

UPS is normal, but 
there is no output to 
the load. 

Check that all power 
cords are properly 
connected. 

If the problem persists consult 
your local dealer for technical 
assistance. 

The UPS switches into 
battery mode and then 
back into utility mode 
when a connected 
device is turned on, or 
the UPS   
switches back and 
forth between battery 
and utility modes.   

1.   A power strip is 

connected to the 
UPS.  
See if there is any 
damage to the utility 
wall receptacle or if 
the cord plug is faulty. 

1. Do not use the power strip.   
2. Replace the wall 

receptacle/cord plug.   

Strange noise or smell  

Immediately shut down the whole 
system. Disconnect the power 
from the UPS and call for 
service. 

UPS is unable to 
provide backup power.

Check that the battery 
connectors are fully engaged. 
Allow the batteries to recharge if 
they are weak. If the problem 
persists after recharging replace 
the batteries. If the problem still 
persists consult your local dealer 
for technical assistance.

Error Codes 

When the Fault LED 

  is lit press the ON button ‘

’ briefly to check the 

error code. The error codes 1, 2, 4, 8, and 16 are represented by the four 
bar LEDs 25%, 50%, 75%, and 100%, and the Overload LED 

. Each 

LED represents a number as shown in the figure below. For example, the 
figure below shows the 25%, 50%, and 100% bar LEDs lit. The error code 
is therefore 8 + 2 + 1 = 11, or Er11, which indicates that the UPS is over-
temperature.
