10) Earthing
The unit has both internal and external earth terminals,
(please see fig 3).
Internal earthing connections should be made to the internal
earth terminal on the PCBA, (please see fig 5 for AC, fig 8 for
DC). The earth conductor should be at least equal in size and
rating to the incoming power conductors. The internal earth
bonding wire connects the PCBA earth terminal to the
internal earth terminal in the enclosure back box.
External earth connections should be made to the M5 earth
stud, using a ring crimp terminal to secure the earth
conductor to the earth stud. The external earth conductor
should be at least 4mm2 in size. The external earth crimp
ring should be located between the two M5 plain washers
provided and securely locked down with the M5 spring
washer and M5 nut.
