RED LED:
on – The PSU supplied with 230V AC voltage
off – no 230V AC mains supply
GREEN LED:
on – DC voltage at the AUX output
off - no DC voltage at the AUX output
3. Operating status indication.
The PSU is equipped with two diodes on the front panel:
4. Operation and use.
4.1 Overload or short circuit of the PSU output (SCP activation).
In case of overload, the output voltage is automatically shut off, and so is the LED indicator. The restoration
of the voltage takes place immediately once the failure (overload) is over.
4.2
Overload or short circuit of the recorder’s module or CCTV camera module.
The modules of the recorder and CCTV cameras are protected against a short circuit by fuses (fuse-
elements). In case of fuse replacement, use a replacement of the same parameters, in conformity with specific
norms and power balance.
4.3 Battery-assisted operation.
The power supply is equipped with deep discharge battery protection (UVP). If the voltage at the battery
terminals drops below 9,5V during battery-assisted operation, the batteries will be disconnected.
4.4 Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the
power supply network. The PSU does not require performing any specific maintenance measures. However, in
case of dust, clean the interior with compressed air. In case of fuse replacement, use a replacement of the same
parameters.
