RED LED:
 on – The PSU supplied with 230 V voltage
 off – no 230 V 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 9,5 V during battery-assisted operation, the batteries will be disconnected.
4.4 Parallel connection of batteries.
The power supply has space for two parallel connected batteries. With this connection, the following rules should
be observed:
- Connect only new batteries: of the same manufacturer, type and the same capacity
- To minimize the rapid flow of current between the batteries, the batteries should be fully charged before connecting
with external charger.
- In the case of low battery, replace always both batteries at the same time.
4.5 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.
