Guidelines
Extending the control panel‘s control
line
The housing for control panel is available in
two versions: for mounting in the wall or for
mounting on the wall. Both versions are de-
signed for a mounting location on the outer
wall of the cabin.
If empty conduits for electrical installations are
already present, this dictates the position of the
control panel.
The cabin wall must be designed in such a way
that the temperature in the area in which ca-
bles are routed cannot exceed 75°C.
The following guidelines apply depending on
the cabin wall:
• Mounting in the wall – insulation:The control
line must only be routed between the insula-
tion and the outer wall of the cabin.
• Mounting in the wall – wooden planks: The
control line is routed between the inner wall
and outer wall of the cabin.
• Mounting on the wall – wooden planks: The
control line is routed along the outer wall of
the cabin.
For longer connections, special RJ10/RJ14 con-
necting cables with lengths of 10 m, 25 m, 50 m
and 100 m are available as an option.
Alternately, the supplied (as standard) 5-m line
can also be extended with an RJ12/RJ12 cou-
pling and an RJ12/RJ12 extension cord.
The extensions and couplings are available as
options.

Mounting location for control panel
Mounting the housing
The control panel is to be mounted outside of
the cabin. Preferably, it should be mounted on
the hinge-side of the door (not the opening
side). This prevents hot air from reaching the
control panel when the cabin is in use, which,
in the event of unfavourable ambient tempera-
tures in the ante-room, could cause condensa-
tion to form on/in the control panel.The follow-
ing distances are recommendations:
The control line from the relay box is connect-
ed to the control panel. The control line is fed
through the opening in the housing. Therefore,
it must be installed once the cut in the wall has
been made.
Tools required:
• Saw for cutting the wall (only when mount-
ing in the wall)
• Phillips screwdriver
• Removal tool to loosen the front panel (in-
cluded in the scope of delivery)
• Taught wire, as needed
• Wooden screws (included in the scope of
delivery):
4 screws for housing mounted in the wall
with a wall thickness of >30mm
3 screws for housing mounted on the wall
Necessary steps:
• Remove the display panel from the hous-
ing
• Mount the housing in the wall, or
• Mount the housing on the wall
