11. WARNINGS AND TROUBLESHOOTING
The alarm messages displayed enable immediate diagnosis.
Alarms are divided into two categories:
• warnings related to the UPS external circuits, (input mains, output mains, temperature and environment).
• warnings related to the UPS internal circuits. In this case, corrective action will be carried out by the After Sales Department.

Warning
Cause
Remedy
A02
OUT OVERLOAD
The power required by the loads is higher than the
power available.
Important!
The accepted overload time limit is defi-
ned in the technical specifications. When
this time limit is exceeded the loads will no
longer be powered by the inverter.
Check that the load is well balanced
over the three phases by checking the
measurements on the display. If neces-
sary disconnect any loads that do not
need continuous power.
A06
VAUX OUT OF TOL
The auxiliary mains supply exceeds the acceptable
tolerance values. Possible causes are:
- No voltage or frequency present or voltage and
frequency outside acceptable values (see the tech-
nical specifications).
- The frequency is subject to continuous variations (typi-
cal with power supplied from an incorrectly sized GE).
A07
OVER TEMPERATURE
The technical plant temperature is higher than the maxi-
mum value recommended.
Check the ventilation or air conditioning
system in the UPS room.
A08
MAINTEN. BYPASS
The output disconnecting switch Q6 is in position 2 (main-
tenance bypass). The load is therefore powered directly
by mains power supply.
A17
IMPROPER USE
This alarm does not indicate a malfunction or failure of
the UPS, but incorrect use/sizing of the system. It is
activated in the event of:
- Operation for long periods at high temperatures
(battery deterioration)
- High number of overloads (wrong sizing)
- Continuous battery discharging (mains not stable)
- High number of switches onto the bypass (high impulsive loads).
A22
MAINS OUT OF TOL
The input mains is not present or not sufficient (voltage
and/or frequency values incorrect with reference to the
technical data)
if there is no input mains outage check
that no protection devices upstream of
the UPS have tripped.
C h e c k t h e v o l t a g e a p p l i e d a n d
frequency values are in compliance
with the values set on the mimic panel.
A38
EXTERNAL ALARM 1
One of the ADC card inputs has been activated.
check the status of the devices
connected to this card.
A39
EXTERNAL ALARM 2
One of the ADC card inputs has been activated.
check the status of the devices
connected to this card.
A40
EXTERNAL ALARM 3
One of the ADC card inputs has been activated.
check the status of the devices
connected to this card.
A41
EXTERNAL ALARM 4
One of the ADC card inputs has been activated.
check the status of the devices
connected to this card.
A61
PHASE ROT. FAULT
The phase cycle sequence is incorrect.
In this case invert two phases of the
input mains. For a UPS with sepa-
rate auxiliary mains exchange the two
phases of the auxiliary mains only.
