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 ‘PE’ terminal. Using the PSU without a
properly made and fully operational shock protection circuit is UNACCEPTABLE! It can cause a
device failure or an electric shock.
4. Connect load/loads to proper output connectors of the power supply (positive pole is marked as +V,
negative pole as -V)
5. Connect the technical outputs to the central or other device.
6. Connect the battery in accordance with the signs (colours).
7. Once the tests and operation control have been completed, the enclosure/cabinet can be locked.

3. Operating status indication.
3.1 LED indication
The PSU is equipped with 3 LEDs on the PCB board:
- red LED (Fig.2, element 1) normal status (AC power): permanently illuminated. AC power absence is indicated by
the AC diode going out.
- green LED (Fig.2, element 2) indicates DC power at the PSU output. Under normal status the diode is permanently
illuminated. In case of a short circuit or an overload, the diode is off.
- green LED (Fig.2, element 3) indicates battery voltage level. Under normal status (U
BAT
> 23V) the diode is
permanently illuminated. In case of decrease of battery voltage (U
BAT
< 23V) the diode is off.
