Electrical wiring
5.1 General notes
n
The devices are operated with 220-240 V/50
Hz alternating current
n
The electrical connection is made using a built-
in mains cable with earthed safety plug
n
Extensions to the connection cable may only
be carried out by authorised electricians, sub-
ject to the length of the cable, connected load
of the unit and taking into consideration how
the unit is used at its location
WARNING!
The electrical connection to the units must be
made at feed-points with residual current
devices in accordance with VDE 0100, Section
704. When installing the units in extremely
damp environments such as laundry rooms,
showers etc., the unit must secured with a
residual current device provided by the cus-
tomer in accordance with the regulations.
CAUTION!
All cable extensions must only be used in fully
un-reeled or reeled off condition.
