Attaching the earthing clamp to the earthing point
Electric shock
Connect the earthing clamp firmly with the earthing point of the panel.
Injury
The mechanism for the shutters on the left and right side in the switching-device
compartment can cause injuries by getting squeezed, caught or cut.
Do not remove any parts of the covering.
Do not reach into the shutter mechanism with hands or tools.
Bolt the earthing clamp hand-tight to the earthing point of the panel using the screw handle.
This corresponds to a tightening torque of approx. 20 Nm.
