Installation
Relay box
The relay box may only be installed outside the
cabin. It is advisable to select the outside wall
of the cabin or the cabin ceiling for the instal-
lation. If ductwork is provided for the electri-
cal installations then the position of the power
switchgear is predetermined by that. Please fol-
low the instructions for installation:
1. Remove the cover of the power ele-
ment. To do this, push the retaining tang
to the inside with a flat screwdriver and
pivot the housing top upwards (Fig. 1).
The 5 mm diameter boreholes for the sup-
plied wood screws 4 x 20 mm are drilled ac-
cording to the dimensions shown in Fig. 2.
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. 3).
3. Hook the power element to the 3 mm pro-
truding screw in the upper mounting hole
Insert the supplied rubber grommet
into the openings at the rear wall of
the housing and insert the connect-
ing cable through these openings.
Fasten the bottom section of the housing
firmly to the cabin wall or cabin ceiling by
inserting the screws into the two lower bore-
holes (Fig. 4).
