exposure to sunlight must be prevented. Protect the unit accordingly if there is an
increased risk of mechanical damage.
Foreseeable misuse
The following are considered instances of foreseeable misuse:
• Incorrect electrical connection.
• The unit is operated without knowledge of or compliance with the safety instructions.
• Operating, service and maintenance requirements are not observed.

Installation
This chapter describes how to install the relay box, the control panel and the most important com-
ponents.
Cables to connect sauna heater, vaporizer (steam generator) or another heating system, light-
ing(s), fan(s) or other components must have appropriate cross section.
All electrical installations and all connecting lines that are installed inside a cabin must be suitable
for an ambient temperature of at least 170°C and protection class IPx4 or be suitable for use in a
steam room (IP 65).
All lines must be routed in such a way that they are well-protected, e.g. in a cable duct.
NOTICE
NOTICE
Damage due to incorrect mounting location
The control unit is not suitable for outdoor use!
• It must be operated only inside buildings and may not be exposed to environmental conditions
such as extreme humidity and moisture or the possible formation of condensation or corrosive
substances in the ambient air, as well as other weather conditions..
• Similarly, excessive cold and extreme exposure to sunlight must be prevented.
• Protect the unit accordingly if there is an increased risk of mechanical damage.
Electronics malfunctions
Routing data and power supply lines together can lead to electronics 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 cable conduits separately.
Requirements for installation site
• Ambient temperature during operation -10°C to +40°C
• Relative air humidity during operation 30% to 75%
• Ambient atmosphere must not be corrosive or have high salt content
• Ambient storage temperature -20°C to +60°C
• Stable wall surface
• Near the place of installation: power supply 400 V 3N ~
• All cables and connections must be accessible for servicing.

Proper and improper mounting of the control unit
WARNING
Risk to life and limb and risk of fire
Risk to life and limb from electric shock and re in the event of improper or faulty electrical con-
nection. This risk also applies following completion of the installation work.
• Do not mount the device in enclosed cabinets or wood panelling.
The device must be installed only outside of the sauna cabin. Recommended installation locations
are:
• Outer wall of the sauna cabin, however not outside of the building
• Plant room or a similar suitable place
If empty conduits for electrical installations are already present, this dictates the position of the
relay box.

This chapter describes how to connect lines to the LSG device’s circuit board.
You can connect sauna heaters for dry Finnish sauna and also Bi-O type heaters. By Bi-O type heat-
ers only the heater section connects to the LSG device. The vaporizer should be connected to the
sauna control unit.
The LSG device is connected with a live current of 400 V 3 N ~ 50 Hz and fused separately with 3 x
16 A. A 16 A cut-out with at least K characteristic must be used for fuse protection.
As a rule, only a xed connection may be connected to the mains supply, whereby a conguration
is provided that makes it possible to separate the system from the mains supply with a contact
opening width of at least 3 mm (all poles).
Recommended installation sequence:
• Connect the sauna heater.
• Connect the control unit.
• Connect the power supply line.
The total power load of connected consumers must not exceed 16 A current per phase.

WARNUNG
Risk of electric shock
A faulty electrical connection poses the risk of an electric shock. This risk remains also after com-
pletion of the installation work.
• Disconnect the system entirely from the mains supply.
• If retrotting is required, the housing must only be opened by trained personnel.
• Electrical installation must only be carried out by a qualied and licensed electrician.
• The unit must be connected to the power supply according to the circuit diagram and the
terminal scheme.
