5.8. Connecting the safety shut-off

EN 60335-2-53 states that sauna control units with a remote start or preset timer
function may only be used for operating and regulating a sauna heater which
has satisfied the combustion test described in paragraph 19.101. Alternatively,
a suitable safety shut-off device can be installed in or above the heater. This shuts
the sauna heater off when objects, e.g. a towel, are placed on the sauna heater.
To install the safety shut-off device, perform the following steps:
1. Install the safety shut-off device in accordance with the operating instruc-
tions for the device.
2. Guide the wires for the safety shut-off device through the cable bushing
into the low-voltage connection area
3. Connect the wires to the terminals labelled "OSG" in terminal strip
If a safety shut-off is not installed, a jumper must be fitted at the terminals
labelled "OSG".
