The internal earth terminal, where fitted, must be used for the equipment
grounding connection and the external terminal is for a supplementary
bonding connection where local codes or authorities permit or require
such a connection.
Once termination is complete, carefully push the cover assembly back
onto the base, avoiding damage to the mating surfaces.
Please Note:
The
cover should be fitted in the orientation as supplied by MEDC to avoid the
cover fouling on the internal components. Replace the 2 off screws into the
holes in the cover assembly and tighten evenly.

mended.
