5.1 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.
1. The assembly's earthing connection clamps must be
connected to the earthing spike by at least 16mm² of
earthing cable (green/yellow). The spike must be driven
into the ground. BG Bau recommends earthing
resistance of
≤ 50 Ω (see BGI 867).
2. Alternatively, a proper earthing device conforming to
VDE 0100-540 can be used (such as the main earthing
line in buildings).
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. Additionally, every work day, the user must check the
mechanical operation of the release by activating the test
button on the residual current protection device (RCD)
(see Fig.
