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. Check the PSU output voltage:
- the PSU voltage without load should amount to U=13,8V DC.
8. 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.
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
> 11,5V) the diode is
permanently illuminated. In case of decrease of battery voltage (U
BAT
< 11,5V) the diode is off.
