POSSIBLE PROBLEMS AND SOLUTIONS

Problems
• When the UPS is switched on, the buzzer sounds
and the red ALARM LED makes intermittent short-
long flashes, then the UPS switches off after 15
seconds
• The UPS works but every 12 seconds there is a
short beep and the yellow BATTERY LED is always
lit up.
• The UPS works but it beeps intermittently, the red
ALARM LED flashes and the yellow BYPASS LED is
always lit up.
• The UPS beeps continuously and the yellow BAT-
TERY LED flashes for about 15 seconds, after
which the UPS switches off.
• The UPS works but the green MAINS LED flashes
quickly
• The UPS beeps intermittently and the red ALARM
LED flashes quickly
If the ALARM LED and / or BYPASS LED are not lit up, the UPS can operate normally although the power
will be reduced.

Solutions
- The connection of the neutral conductor is wrong:
invert the power supply plug, or exclude the neu-
tral sensor (using the UPS SuperviSor light soft-
ware supplied)
- Check power is present at the mains socket.
- Check that the UPS power supply cable is correc-
tly inserted in both the mains socket and in the
UPS connector
- There is an overload on the UPS output. Reduce
the quantity of appliances connected so that the
load does not exceed the maximum power that
the UPS can supply.
- The UPS has completely flattened its batteries; it
can only start up again when the input line is pre-
sent. Check the magneto-thermal or differential
switches that precede the UPS
- The mains supply is out of the limits permitted for
the voltage and/or frequency, but it can still be
used by the UPS. However, the bypass function
is not operational.
- The thermal protection has intervened. Switch the
UPS off and wait for a few minutes so that the in-
ternal temperature of the UPS can get back to
normal. Check that the fans operate correctly and
that the relative airflow is not obstructed (e.g. if
the UPS is too close to a wall).
- There is a fault on one of the internal circuits. Con-
tact your nearest service centre.
