2.10 Mains connection

The sauna heater must be connected to the mains by a qualified electrician and in compliance with current regula-
tions. Sauna heater is connected with a semi-permanent connection. Use A07BB-F or 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 (Image 6 Location for the con-
nection 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.
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.

2.11 Electric heating toggle

Electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked 55) for controlling the electric heating toggle. Connectors
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.
