PE-measuring point
In accordance with the applicable German safety regulations (Accident Prevention and
Insurance, BGV A2/A3), electrical installation and equipment have to undergo inspection
at regular intervals. For this purpose, the fixing screw of the 5-pin DMX socket may serve
as measuring point for the insulation and fault current measurement. This screw is
connected to all sheet metal parts by means of a contact disc.
