The circuit of the shock protection shall be performed with a particular care, i.e. the
yellow and green protection wire of the power cable shall be connected from one side to
the terminal marked by the symbol of
in the casing of the power-supply. Operation of
the power-supply without the properly made and fully operational circuit of the shock
protection is UNACCEPTABLE! It can result in failure of devices and electric shock.
4. Connect the loads cables to the terminals V + (+), GND (-) of the power supply module.
5. Connect the power (~230V)
6. Connect the battery in accordance with the markings (colours):
- battery output (+V): BAT+ cable / red,
- battery output (0V): BAT – cable / GND / black.
7. Check the power supply operation indicator: LED diode (green on the power supply module).
8. Check the power supply output voltage:
- the unloaded output voltage should be U=13.8V DC.
9. After installing and checking the proper function of the power supply, the case can be closed.
3. Indication of power supply operation status.
3.1 Optical indication of operation status.
The power supply is equipped with an optical indicator of the output voltage state.
LED diode (green) on the PCB panel indicates:
- Lit = DC voltage at the power supply output
- Not lit = no DC voltage at the power supply output
4. Service and use.
4.1 Overload or short circuit of the power supply output (SCP operation).
In the case of overload of the power supply an automatic disconnection of the output voltage takes place,
signalled by the shut off of the LED diode. The return of voltage will take place automatically after the failure
(overload) is corrected.
4.2 Disconnection of discharged battery.
The power supply includes a disconnection system for discharged buffer batteries. During the battery’s
operation, a lowering of voltage at the battery terminals to below 9.5 V causes battery disconnection.
4.3 Maintenance.
All maintenance procedures can be performed after the disconnection of the power supply from the
electrical grid. The power supply does not require any special maintenance procedures, but in the case of
significant dust accumulation, dusting using compressed air is recommended.
