2.11. Connection of the sauna heater to the mains

The sauna heater must be connected to the mains by a qualified electrician and in compliance with current regulations.
Sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66) cables or a corresponding
type. Other output cables (signal lamp, electric heating toggle) must also adhere to these recommendations. Do not use
PVC insulated cable as a connection cable for the sauna heater.
A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control current fuse, the
diameter of all cables must be the same, i.e. in accordance with the front fuse. For example, in an 8 kW sauna heater the
diameter of separate cables to the signal lamp and the mains control unit has to be at least 2.5 mm².
The connecting box on the sauna wall should be located within the minimum safety clearance specified for the sauna
heater. The maximum height for the connection box is 500 mm from the floor (figure 5 Location for the connection box,
page 9). If the connection box is located at 500 mm distance from the heater, the maximum height is 1000 mm from the
floor.
NOTE: Controlling the lights in the sauna with the circuit board is only possible with resistive loads (incandescent light
bulbs). The circuit board relay cannot withstand capacitive loads (switched-mode power supply units). If the lighting fixtures
in the sauna have transformers, for example LED or halogen lamps, the stove circuit board's relay control must be fitted
with a separate relay or contactor for controlling the lights.
Sauna heater insulation resistance: The sauna heater heating elements may absorb moisture from air, e.g. during storage.
This may cause bleeder currents. The moisture will be gone after a few heating sessions. Do not connect the heater power
supply through a ground fault interrupter.
Adhere to the effective electrical safety regulation when installing the sauna heater.

2.12. Electric heating toggle

Electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked N-55) for controlling the electric heating toggle. Connectors N-55 and the heating
elements are simultaneously live (230V). The sauna heater thermostat also controls the heating toggle. In other words,
home heating turns on once the sauna thermostat cuts power off the sauna heater.
