WARNING
Do not use the device without grounding
To operate the device safely, the grounding connector must have a suitable cable
connected. Do not use the device without a grounding cable connected.
The ground connector is located on the rear of the device (M4 thread, max. screw length 20
mm). Connect the grounding cable before you mount the device on a wall or on the optional
mounting plate. Once the device is mounted, this connector is no longer accessible.
Place the supplied toothed washer directly on the rear of the device before screwing on the
ground cable. Only then can you be sure that there is ideal contact with the screwed-on
cable.
