3.3. Electrical connections
The electrical connection of the device must be installed by a qualified electrician in accordance with applicable standards and requirements.
• The connection of the sauna climate unit must be done semi-stationarily on the wall of the steam room of the connection box. The junction box must be
splash-proof and have a maximum height of 500 mm from the floor.
• The connection cable must be a rubber insulated cable type H07RN-F or equivalent.
• The electrical connection of the device must be set up by a qualified electrician in accordance with applicable standards and requirements.
• The connection of the sauna climate unit must be done semi-stationary to the connection box on the wall of the steam room. The connection box must be
sprayproof and can have a maximum height of 500 mm from the floor.
• The connection cable must be a rubber insulated cable type H07RN-F or equivalent.
To access the electrical connections of the device, it is necessary to open the panel under the stone box. To open the panel, completely loosen the two bolts under
the device ( Figure 4 ). The bolts on the sides must also be slightly loosened for better access ( Figure 4 ).
Attention! Due to thermal cracking, it is forbidden to use PVC insulated cable as the connection cable for the sauna climate device.
• The internal connections of the device are made using screw terminals pursuant to figure 2 and table 1 in this manual.
• A protective earth (PE) connection with conductors of at least 2.5 mm2 must be connected to the connection terminal of the device.
• The heater must be powered from a 380 VAC (3-phase) or 230 VAC (1-phase) 50/60 Hz power supply via a control device protected by an overcurrent
protector of the size shown in table 1.
• If the device’s air circulation fan is to be connected separately from the heater control device, the fan must be connected via a residual-current device.
In this case, the PE power fan inlet terminal (PE) earthing must not be combined with the heater power terminal protective earth. Also, in this case, use earthed
cables of at least 1.5 mm2 to power the fan.
• The power supply cable must enter the housing of the sauna climate device in a way that prevents water from leaking into the housing of the device and into the
connection box on the wall along the cable. The outer insulation (sheath) of the cable may only be peeled off inside the housing.
• If the connection and installation cables are higher than 1000 mm from the floor of the steam room or inside the steam room walls, they must be able to
withstand at least 170 °C (eg SSJ) under load. Electrical installations more than 1000 mm above the floor must be approved for use at 125 °C (T125 marking).
• The recommended cross-section of the connecting cable grooves is shown in Table 1 (page 16).
NB! The sauna climate device may only be connected by a qualified electrician in accordance with applicable regulations.
3.3.1. Electric heater insulation resistance
Upon final inspection of the electrical installation, you may detect a ‘leak’ by measuring the insulation resistance of the sauna climate device. This is because the
insulating material of the heating elements has absorbed moisture from the air (storage, transport). After using the sauna climate unit a few times,
this moisture disappears.
Do not connect the heater to the mains through a residual-current device!
