8. 2. CONNECTING THE POWER CABLE
As the only one,
the power cable can be plugged or unplugged only when the unit is off. The unit conforms to
class I electric shock protection and requires one phase power supply with sockets equipped with a
grounding pin. The power supply socket is located on the back panel of the casing (Fig. 5, item 13).
In order to avoid the risk of electric shock, the unit must be connected to the mains with
protective grounding.
The unit does not need to be connected to an additional protective earth contact (Fig. 5, item 11). An
additional protective earth contact serves to ground the unit when an ungrounded power socket is used or at
places where a shock protection system requires the connection of an additional equipotential bonding
conductor.
