Installation
Power supply / Power supply unit
The power supply unit is designed for 100V to 240V AC (50-60 Hz). It is supplied with four change
adapters enabling virtually worldwide use. Where necessary, connect the plug normally used in your
country to the power supply unit. There are two versions of the plug-in power supply unit that are
connected slightly differently:
Version 1: Set the switch on the power supply unit to OPEN and push out the existing plug upwards.
Then insert the new plug required into the power supply unit and lock it with the switch (LOCK).
Version 2: Remove any existing plug by pressing OPEN. Then insert the required new plug into the
power supply unit at a slight angle with the label TOP upwards. Press downwards until it snaps into
place.
