Installing the solar system
!
WARNING! Electrocution hazard
Completely cover all solar panels with an
opaque material during installation to
prevent electricity from being gener-
ated.
A
NOTICE! Damage hazard
Ensure that the junction box and the roof
duct are properly sealed and that the roof
duct is glued tightly to the roof so that no
moisture can leak into the junction box or
through the roof.
Installation location
When selecting the installation location, consider
the following:
• The mounting surface must be even and stable
enough to support the solar panel.
• Ensure that the designated mounting surface is
sufficiently dimensioned.
• Ensure there is enough room to access the solar
panels and other fixed components for mainte-
nance.
• Ensure that any existing ventilation openings on
the vehicle and the rear ventilation of the solar
panel are not blocked.
• Shading can reduce the performance of the
solar system. Ensure that fixed components,
such as air conditioners or opened satellite
antennas, do not shade the solar panels.
• Choose a location with direct sunlight for opti-
mal performance.
• Place several solar panels as close to each other
as possible.
• Do not glue the side roof mounting supports or
roof ducts to rubberized surfaces (e.g. exterior
planking), as the adhesion of the glue is not guar-
anteed.
Preparing the installation
➤Mark and prepare the bonding surfaces, see
fig. 4, page 5 to fig. 7, page 5.
➤Strip the cable ends as follows (fig. 8, page 5):
– Outdoor cable 11 mm (4.0 mm²)
– Indoor cable 11 mm (4.0 mm²)

Connecting the solar panel (fig. 9,
page 5 to fig. 0, page 6)
Observe the following instructions when connect-
ing the solar panel:
• Seal the unused cable outlet on the junction box
(1) with the blind plug (2).
• Only use the outer terminals on the junction box.
• Only connect solar panels of the same type and
capacity.
• Connect two solar panels to the one junction
box closest to the roof duct.
Connect the solar panel as follows:
➤Connect the outdoor cable to the junction box
"
(A, fig. 9, page 5).
➤Connect several solar panels as follows in
parallel (B, fig. 0, page 6):
– Connect the positive poles with each other.
– Connect the negative poles with each other.
Mounting the solar system
!
WARNING! Risk of injury
Do not use silicone or any other adhesive
than the one supplied.
A
NOTICE! Damage hazard
Before drilling any holes, make sure that
no electrical cables or other parts of the
vehicle can be damaged by drilling, saw-
ing or filing.
➤To mount the solar system, proceed as shown in
fig. a, page 6 to fig. f, page 7.

NOTE
The cable length should be as short as
possible.
➤Connect the outdoor cable to the indoor cable
at a suitable point using the cable connector (1).
