Switching the ADN PS power supply on/off
The ADN PS power supplies can only be switched on when the central unit and the previous ADN PS connected in series are also switched on.
You can set up your conference system so that you can increase or reduce the number of conference units used by simply switching individual ADN PS on or off.

Switching the conference system off
Set the on/off switch 1 of the ADN CU1 central unit to position “0”.
The central unit is switched off and the display panel goes off. All ADN PS power supplies connected to the central unit and switched on are switched off and the status LEDs go off.
To switch individual ADN PS power supplies off:
Set the on/off switch 2 of the ADN PS power supply to position “0”.
The power supply is switched off and all status LEDs go off. Additional connected ADN PS power supplies are also switched off.
To completely switch the ADN CU1 central unit or the ADN PS power supply off:
Disconnect the mains connector of the ADN CU1 central unit or the mains connector of the ADN PS power supply from the mains power supply.
