TROUBLESHOOTING GUIDE 

Irregular operation of the UPS is very often not an indication of a fault but is simply caused by simple problems or distractions. 
We therefore recommend you consult the table here below, which provides some information that will help you to solve the most 
common problems. 
 

 

WARNING:

 Table 10 below frequently recommends the use of the maintenance BYPASS. We remind you that before 

restoring the UPS to operation, you must make sure that it is on and 

not in STAND-BY

. 

If the UPS is in this latter mode, turn on the UPS by accessing the “SYSTEM OFF/ON” menu and wait for the power-on 
sequence to be completed before removing the maintenance BYPASS. 
For further details

 read the procedures described in the

 

maintenance BYPASS (SWMB

) chapter.

 

 

NOTE:

 For a detailed explanation of the codes listed in table 10, see the “STATUS/ALARM CODES” chapter. 

 

PROBLEM 

POSSIBLE CAUSE 

SOLUTION 

THE UPS IS COMPLETELY 

OFF 

 

(THE DISPLAY IS NOT 

TURNED ON) 

MAINS VOLTAGE NOT PRESENT 

(BLACKOUT) 

Check that the mains voltage is present. If necessary, power 
on the UPS from the battery to power the load. 

NO CONNECTION WITH INPUT 

TERMINALS 

Connect  the  mains  to  the  terminals  as  indicated  in  the 
Installation manual. 

INPUT BREAKER (SWIN) IS OPEN 

Close the input breaker (SWIN). 

NO NEUTRAL CONNECTION 

The  UPS  cannot  work  without  a  neutral  connection. 
WARNING:  If  this  connection  is  missing,  damage  could  be 
caused to the UPS and/or the load. 
Connect  the  mains  to  the  terminals  as  indicated  in  the 
Installation manual. 

UPSTREAM PROTECTIVE 

DEVICE OPEN 

Reset the protective device. Warning: check that there is no 
overload or short-circuit at the output of the UPS. 

THE LOAD IS NOT 

POWERED 

NO CONNECTION WITH OUTPUT 

TERMINALS 

Connect the load to the terminals. 

OUTPUT ISOLATOR (SWOUT) IS 

OPEN 

Close the output isolator (SWOUT). 

UPS IS IN STAND-BY 

Execute the power-on sequence. 

STAND-BY OFF MODE IS 

SELECTED 

The  operating  mode  must  be  changed.  In  fact,  STAND-BY 
OFF (emergency) mode only powers the loads when a black 
out occurs. 

UPS FAILURE AND AUTOMATIC 

BYPASS OUT OF ORDER 

Insert  the  maintenance  bypass  SWMB  (if  present)  and  call 
your local service center. 

THE UPS RUNS ON 

BATTERY POWER EVEN 

WHEN THE MAINS 

VOLTAGE IS PRESENT 

UPSTREAM PROTECTIVE 

DEVICE TRIPPED/BLOWN FUSE 

Reset the protective device or replace the blown fuses. 
WARNING: Check that there is no overload or short circuit at 
the output of the UPS. 

INPUT VOLTAGE OUTSIDE 

TOLERANCE LIMITS FOR MAINS 

OPERATION 

Verify  the  voltage  measures  in  the  “Mains  Input  page”. 
Problem caused by the mains. Wait for the input mains voltage 
to  return  within  the  tolerance  limits.  The  UPS  will  return 
automatically to mains operation.
