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.
Caution! LED indicates power absence if the outage lasts >10s.
- 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.
