4. Operation and use.
4.1 Overload or short circuit of the PSU module output.
The AUX output of the PSU module is equipped with the PTC polymer fuse assisted protection. If the load
of the PSU module exceeds I
max
(load 110% ÷ 150% @25ºC of the PSU module power), the output voltage is
automatically cut off and indicated by the green diode going off. To restore the output power, cut off the output load
for approximately 1 minute.
In case of of the short-circuit to the AUX, BAT output, or incorrect connection of the battery, the fuse F
BAT
in
the battery circuit becomes permanently damaged and the restoration of the voltage at the BAT output requires the
replacement of the fuse.
4.2 Battery-assisted operation
In case of a main power outage, the device is immediately switched into a battery-assisted operation.
The PSU module is not equipped with a discharged battery disconnection system.
4.3 Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU module from the
power supply network. The PSU module does not require performing any specific maintenance measures, however, in
the case of significant dust rate, its interior is recommended to be cleaned with compressed air. In case of fuse
replacement, use a replacement of the same parameters.
