POSSIBLE PROBLEMS AND SOLUTIONS

Problems
• When the UPS is switched on, the buzzer sounds
and the red Status Indicator makes intermittent
short-long flashes, then the UPS switches off
after 15 seconds
• The UPS works but every 20 seconds there is a
short beep and the yellow Status Indcator is
always lit up.
• The UPS works but it emits an alternating, slow-
fast intermittent sound, the red Status Indcator
flashes fastly
- The UPS beeps continuously and the Status
Indicator is continuosly yellow, after which the
UPS switches off.
• The UPS works but the green Status Indicator
flashes quickly
• The UPS emits an alternating, slow-fast
intermittent sound, and the red Status Indicator
flashes quickly
Solutions
- The connection of the neutral conductor is wrong:
make a 180° inversion of the power supply plug,
or exclude the neutral sensor (using the UPS
Communicator software supplied)
- Check that power is present at the mains socket.
- Check that the UPS power supply cable is
correctly 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
present. Check the magneto-thermal
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 thermic protection has intervened. Switch the
UPS off and wait for a few minutes so that the
internal 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.
Contact your nearest service centre.
