Power element
The power switchgear may only be installed
outside the cabin. It is advisable to select the
outside wall of the cabin or the cabin ceiling for
the installation. If ductwork is provided for the
electrical installations then the position of the
power switchgear is predetermined by that.
Please follow the instructions for installation:
1. Remove the cover of the power element
by pushing the retaining tang to the in-
side with a fl at screwdriver and pull the
housing top upwards in a swinging fa-
shion (Fig. 1).
The 5 mm diameter boreholes for the
supplied wood screws 4 x 20 mm are
drilled according to the dimensions
shown in Fig. 3.
2. Insert one of the wood screws into the
top center hole. The power element is
hooked onto this screw. Therefore, leave
the screw out by ca. 3 mm (Fig. 4).
3. Hook the power element to the 3 mm
protruding screw in the upper mounting
hole.
Insert the supplied rubber grommet
into the openings at the rear wall of the
housing and insert the connecting cable
through these openings.
