FI protection switch
The FI protection switch option can only be supplied by the
factory.
The FI protection switch (RCD) is a protective measure against
dangerous body currents according to DIN VDE 0100-551.
Earthing requirements:
1. The assembly‘s earthing connection clamps must be
connected at least 16 mm
2
of earthing cable (green/yellow)
connected to the earthing spike. The spike must be driven into
the ground. BG Bau recommends that an earth resistance of
≤
50
Ω
is used (see BGI 867 regarding this).
2. Alternatively, a proper earthing device conforming to VDE
0100-540 can be used (such as the main earthing line in
buildings).
Attention!
1. The effectiveness of this protective measure must be
checked at least once a month by an electrical expert or, if
suitable measuring and testing devices are available, by an
electrotechnically trained person under the guidance and
supervision of an electrical expert.
2. The user must also check the mechanical operation of the
release every working day by activating the test button on the
residual current protection device (RCD)
(see Figure 5-1-
(10))
