1.2.9 Earthing connection

The protective earth conductor of the lead must be attached to

the central earthing point by way of a ring lug.

After installation, ensure proper metal contact of all aluminium

parts, i.e. the cable lug and/or metal part (check by measur-

ing)

If necessary, mill off any aluminium parts at the contact point

to ensure proper conductivity (the resistance of the earth con-

ductor must not exceed 0.1 ȍ)

After connecting the earth conductor, proceed as follows:

Check the strain relief clamps for proper fit

Check to make sure the cables leading to the connection ter-

minals are properly placed in accordance with applicable

norms

Perform a visual check of the insulation to ensure it is in

proper condition
