Lid Earth Screw Assembly
Attach the earthing line's cable lug to the earthing screw. Then place a
spring washer over it, followed by a hex nut. Tighten the nut (up to a maxi-
mum torque of 7.5 Nm).
Close the enclosure
When re-closing the enclosure cover, be sure that:
• All screws and bolts for the earthing and housing are fully tightened.
• The enclosure cover, the cover seal and the surrounding area are clean
and free of dust.
• The enclosure cover is properly aligned with the enclosure base.
• The enclosure cover is properly seated and all cover screws are
tightened.
