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. The
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.
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. See page 10 Image 4 Location for the connection box
If the connection box is located at over 500mm distance from the heater, the maximum height is 1000mm from the floor.
Sauna heater insulation resistance:
The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leakage currents. The
moisture will be gone after a few heating sessions. Do not connect the heater power supply through a ground fault interrupter.
However, adhere to the effective electrical safety regulation when installing the sauna heater.
