The earth connection must be made with the largest possible cross-
section, with a low impedance, over a large area and via a short
connection to large conductive fastenings. Beckhoff recommends
the use of wide connections with large contact surfaces. Wide earth
straps are suitable for this. The table below illustrates typical suit-
able connectors:

Make sure that an optimally conductive connection is available at
the connection point for the protective conductor. To ensure this,
carefully remove paint, dirt, corrosion and all insulating components.
Use galvanized stud bolts and washers.
