FI circuit breaker
The FI circuit breaker option can only be supplied by the fac-
tory.
The FI protection switch (RCD) serves as a protective meas-
ure 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 an
earthing resistance of ≤ 50Ω (see BGI 867).
2.
Alternatively, a proper earthing device conforming to
VDE 0100-540 can be used (such as the main earth-
ing line in buildings).
WARNING!
The generator must be earthed.
In this special case the generator must be earthed! The
above-mentioned safety warnings with other wording are
not relevant for this special fitting.
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 un-
der the guidance and supervision of an electrical ex-
pert.
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)
(seeFigure 5-2 -10))
