Installation
This chapter describes how to install the relay box.
In a multi-cabin installation, all data lines and power supply cables must be
routed and plugged in before installing the relay boxes and control units.
NOTICE
Equipment damage
Corrosive environments or environments with high levels of saline
in the air could damage lines and circuit boards.
Use the power unit only in non-corrosive environments.
Salt aerosols should only be used inside the cabin.
4.1 Power supply and data lines
All electrical installations and all connecting lines routed inside the cabin
must be suitable for an ambient temperature of at least 70°C in infrared-
only cabins.
All lines must be routed in such a way that they are well-protected, e.g. in a
cable conduit.
NOTICE
Electronics malfunctions
Routing data and power supply lines together can lead to elec-
tronics malfunctions because, e.g. because the sensor will not be
detected.
Do not route sensor and sauna bus lines together with power
supply lines.
Route separate cable conduits.
Line routing
The lines from the individual components to the power unit may not
exceed 5.5 m in length.
If you connect more than one emitter per heating circuit, you must termi-
nate the corresponding lines in the on-site plug-in modules outside the
relay box. See
Example – plug-in modules (optional),
The control line must only be routed between the insulation and the outer
wall of the cabin. Cabin insulation must be installed in such a way that the
temperature in the area in which cables are routed cannot exceed 75°C.
