A21 OVERTEMP
Inverter module heatsink temperature is highcheck the followings:
-If UPS air inlets and outlets covred by dust clean
-If any material prevents air flow at UPS air inlets or outlets take the material
-If UPS ambient temperature is high then 45 C, use air cooling system
A22 OUTPUT OFF
During mains failure if the battery backup time is finished this message is normal ,there is no energy so the
UPS shutdown the output voltage.
If this message is permanent call service, otherwise wait until the message is deleted automatically from
LCD screen.
A23 ON BYPASS
From any reason UPS transferred the load to bypass, check the other alarm code which shown together
with this alarm it shows the by-pass reason.
If the UPS stays at this position for a long time call service.
A24 REVERSE CURRENT
Any load such as motorsa are connected to UPS output and the load in regenerative mode ,it is applying
reverse energy to the UPS output. Call service
A25 INV RESET
This is the power on indicator of the inverter modüle, during ower on for 10 seconds this message will be
shown at the end of 10 seconds the mesage will be cleared.
A26 BATTERY LOW
The DC BUS or battery voltage of the UPS is low, still UPS is running but DC voltage is going down.
If this alarm occures during mains failure it means that there is no energy from batteries this is normal.
But if this alarm occures during mains OKEY call service.
A27 GENERATOR MODE
UPS is running in generator mode when generator set stops UPS returns to normal operating mode
automatically.
A28 O/P PHASE LOSS
Call service
A29 SYNCHRON BAD
This is only warning that showa the inverter and by-pass voltages are not synchron to each other ,there is
nothing to do wait until they matches.
A30 SHORT CIRCUIT
Shorter then 4 alternance (40 milliseconds) short circuit occured at theoutput of the UPS, now UPS
isrunning but you must check the installation and loads.

A32 SERVICE LOGIN
Service ersonnel logged in to UPS this is only warning.
A34 BYP ROTATE PHASE
The phase sequency of the by-pass source is not match the UPS output phase sequency. Please check
the by-pass phase sequency if wrong change phases.
A35 INV STOP
The message shows that the inverter modüle stopped from any reason ,check the other alarm code which
is shown together with this mesage.
