The strip should be inserted so that it projects up 3 - 4 mm in the slot area where the front
and rear panels will rest.
After the second or subsequent bottom plates are put into place, the plates should be firmly
bolted together using M16 x 40 nuts and bolts. After this, a flexible earthing cable must be
bolted in the angle bar of one of the slots in order to make up the earthing ring.
