Whenever a malfunction occurs, first check external factors (e.g. connections, temperature, humidity or load) to
determine whether the problem is caused by the unit itself or by its environment. Subsequently check whether
the MCB/switches on the rear panel (fig. 12, 7-8-9) are in 'on' position. Always check these external factors
before concluding that your UPS is faulty.
The front screen will indicate the problem and solution (if the problem is due to environmental circumstances). If
the solution is not shown on the screen, please contact your dealer.
During the self-test, performed immediately after start-up, the UPS may detect a system failure. In this case a
message is displayed for 30 seconds before the self-test is repeated. If the faulty situation persists, please
contact your dealer.
(One of) the following messages can be displayed:
SELFTEST FAILURE
PCB POWER SUPPLY
SELFTEST FAILURE
AC ON INPUT
SELFTEST FAILURE
INT.BATTERY FUSE

Q4 NOT OK
* If absence of input power (utility failure, maintenance work) is expected to last longer than a few hours, switch
off the UPS to save battery power. If the UPS input power is absent for several days and the UPS remains on
under no-load conditions, the batteries can be discharged very deeply, resulting in a short battery life time.
