RED LED:

 on – the PSU is supplied with 230V AC

 off – no 230V AC supply

GREEN LED:

 on – DC voltage in the AUX output of the PSU

 off – no DC voltage in the AUX output of the PSU

2.2 Installation procedure.

1. Before installation, cut off the voltage in the 230V power-supply circuit.

2. Mount the PSU in a selected location and connect the wires.

3. Connect the power cables (~230Vac) to L-N clips of the PSU. Connect the ground wire to the clip marked by the

earth symbol PE. Use a three-core cable (with a yellow and green PE protection wire) to make the connection.

Lead the cables to the appropriate clips through the insulating bushing of the connection board.

The shock protection circuit shall be performed with a particular care, i.e. the yellow and

green wire coat of the power cable shall stick to one side of the terminal - marked with

‘ ‘ symbol on the PSU enclosure. Operation of the PSU without the properly made and

fully operational shock protection circuit is UNACCEPTABLE! It can cause a device

failure or an electric shock.

4. Connect the receivers’ cables to the terminals V+ (+), V-(-) of the PSU module.

5. Connect the power (~230V)

6. Connect the battery (mind the colours):

- battery output (+V): BAT+ cable / red,

- battery output (0V): BAT – cable / GND / black.

7. Check the PSU operation indicator: green LED.

8. Check the PSU output voltage:

- the PSU voltage without load should amount to U=13,8V DC.

9. After installing and checking proper working, the enclosure can be closed.

3. Operating status indication.

3.1 LED indication of operating status.

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 on)

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 after the failure (overload) is over.

4.2 Disconnection of discharged battery.

The PSU is equipped with the discharged battery disconnection system. During the battery-assisted

operation, reducing voltage below 9,5V at the battery terminals will cause battery disconnection.

4.3 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 significant dust rate, its interior is recommended to be cleaned with compressed air.
