The mounting plate should always be screwed and glued on. Alternatively, having a certifi ed specialist dealer
glue on the mounting plate professionally may eliminate the need for screwing it on.
1. Place the mounting plate on the roof of the vehicle so that the centre hole is aligned centrically to the cable gland.
The
arrow symbol
must be visible from above and point forwards in the
direction of travel
(see
Aligning the moun-
ting plate, p. 13
).
2. Mark out the positions of the six circularly arranged mounting holes on the vehicle roof.
3. If the roof panel material is very thin and the insulation material does not provide suffi cient support either, drill
through holes (Ø 5.5 mm) into the interior of the vehicle and use suffi ciently long galvanised M5 round head screws.
Make sure to use a suffi ciently strong counter support that can withstand the bolt loads (large washer or reinforcing
plate).
4. Drill the holes required for fi xing the mounting plate (see
Fixing the mounting plate, p. 13
).
5. In addition to screwing on the mounting plate, support and roof gland, glue them onto the roof and seal them. To do
this, use a sealing adhesive which is suitable for this purpose (e.g. DEKAsyl MS power adhesive). Pay attention to the
following:
–
Before working with the sealing adhesive, carefully read through the safety data sheet and the technical
data sheet of the sealing adhesive!
– To ensure good adhesion, ensure that the surface is clean, dry and free of grease. Clean the roof surface in a radius
of 35 cm around the borehole with a suitable cleaning agent and allow the surface to dry well.
6. Proceed as follows when gluing on the mounting plate and the support:
– Before starting to work with the sealing adhesive, ensure that the processing temperature of the materials to be
glued together and the sealing adhesive is b5 °C and +35 °C. Prepare all necessary fastening elements
and tools.
– Prepare the sealing adhesive according to the enclosed instructions.
– Pull out the roof gland (see
Installing the cable gland, p. 13
) and apply the sealing adhesive evenly to the under-
side of the roof gland fl ange.
– Insert the roof gland into the drilled hole and press it against the vehicle roof.
– Apply the sealing adhesive evenly to the underside of the mounting plate, completely covering the area inside the
circular groove (see
Applying adhesive, p. 13
). Glue this area completely to the vehicle roof to achieve the neces-
sary bonding force.
– Place the mounting plate on the vehicle roof as you did before for marking the drill holes. Make sure that the arrow
on the mounting plate points in the forward direction of the vehicle and that the fastening holes are aligned with
the drilled holes.
– Fasten the mounting plate using the prepared screws, evenly tightening the six screws in a diagonal sequence.
Material damage by overtightening the screws!
The sealing adhesive will fi ll small gaps resulting from the curvature of the vehicle roof. Applying too
much force when tightening the screws may bend the mounting plate.
►
Tighten the screws carefully.
– Use a clean colourless cloth to remove any sealing adhesive leaking from the sides. Pay attention to the following:
○ Do not use cleaning agents or thinners containing solvents, as this could damage the sealing adhesive applied
underneath the mounting plate.
○ Soak the cloth in acetone or MEK. Test acetone or MEK on an inconspicuous spot fi rst to be sure that it does not
damage the surface.
○ Use only cleansing paste and water to clean your hands.
– Fasten the cable gland. To do this, screw on the enclosed knurled nut from inside the vehicle (see
Installing the
cable gland, p. 13
).
– Note that the curing of the sealing adhesive depends on the ambient temperature and humidity. The fi nal adhe-
sive strength can be found in the data sheet of the sealing adhesive. However, the next installation steps can be
carried out without delay as the mounting plate is held by the screws.
