Power switchgear installation instructions
The standard power switchgear supplied is rated at 380-400 V AC (3N) and a maximum switching
capacity of 35 A per phase and features a safety shutdown mechanism if installed together with
our sauna control units.
Only a qualified electrician working for an authorised electric company and taking ac-
count of VDE 0100 Part 703 may install and hook up sauna equipment and other electric
utilities. All mains connections of sauna equipment must be stable and steady.
Caution: The unit may not be installed in closed cabinets or in an enclosed timber clad-
ding! Ventilation is compulsory! Vertically screw the switchgear to the wall! Do not place it
on the cabin roof!
• Mount the power switchgear on a wall of the room the sauna cabin is installed in or of the en-
gineering room. Do not mount this piece of switchgear on a wall of the sauna cabin because
switching of the contactors may produce a lot of noise.
• Study the control unit installation instructions to mount the unit on a wall outside the sauna
cabin; the best place is next to the cabin door. Attach the sensor housing and the sensor wires
inside the sauna cabin (as described in these instructions).
• Do not install the sensor and power supply lines together or put them through the same feed-
through opening. Installing them together may produce faults in the electronic circuitry and
"wobbling" contactors. If installing them together, use a shielded sensor wire, e.g. LIYLY-0 4x0.5².
Check that the shield in the control unit is connected to earth. In case the sensor wires in the
package are not long enough to interconnect the control unit and the sensor housing in the
cabin, check that the wire you use instead is shielded, e.g. LIYLY-0 4x0.5².
• Attach a heat-resistant cable to the sauna heater and place the heater inside the cabin with its
back in front of the air inlet.
• Check that all connecting cables installed inside the cabin are rated to withstand temperatures
of at least 140°C.
• Connect the entire system to the mains as shown on the wiring diagram. Consider the regula-
tions of the local power utility, the VDE, § 49 Da/6, and VDE 0100 Part 703. Only have a locally
certified electrician do the electrical installation.
