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 1A (load 110% ÷ 150% @25ºC of the PSU module power), the output voltage is
automatically cut off and indicated by the green diode going out. To restore the output power, cut off the output
load for approximately 1 minute.
In case of a short-circuit in the AUX, BAT output, (load 200% ÷ 250% of the PSU module power) or reverse
battery connection, the F
BAT
fuse 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 the main power outage, the device is immediately switched into a battery-assisted operation.
In order to run the PSU module from the battery only, connect the BAT connectors in accordance with the
signs:
+ BAT red to ‘plus’ and, - BAT black to 'minus’ then press the START button on the main board and hold it for 5
seconds.
The PSU module is equipped with the discharged battery disconnection system (UVP).
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 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.
