2 Installation and electrical connection –
only for qualified professionals
Damage to the device: do not install the control unit wtih a cordless screwdriver!
Risk of breakage!
2.1 Installation of operating unit
Drill a hole of a diameter of 30 mm at the desired position using a hole saw and insert the operating unit. Affix at
the positions shown in Fig. 2A with the bolts contained in the scope of supply.
2.2 Installation of power unit
Affix the power unit at the positions shown in Fig. 1 H with the bolts contained in the scope of supply.
2.3 Electrical connection
2.3.1. Socket allocation Fig. 1 / Fig. 3
Terminal X1:
INPUT: mains supply line. The fuse must be positioned externally in accordance with Figure 3
OUTPUT: connection load: 230V AC1
ENABLE: enable input
Connector X2: operating unit connection.
2.3.2 Connection of the STL (safety temperature limiter) –
signals of a sauna control unit
This is an indirect STL. Devices which are not inherently safe must not be operated on
the switchbox.
The STL signal can be incorporated via the ENABLE input of the switchbox. When 230V is exerted on ENABLE,
the switchbox unblocks the output. See also Point 3.1.2 - Enable
2.3.3 Remote start of sauna and infrared devices with potential-free remote
start contact (Fig. 4)
For devices without 230V remote start input, the remote extension WC4-SB-REM is necessary.
Where sauna heating devices are directly operated on the switchbox, it must be ensured that
they are inherently safe. The switchbox has no safety temperature restriction.
