7.3 Earthing
Fig 4: Earth Locations
The unit has both a primary internal and secondary external earth
fixing point.
Internal earthing connections should be made to the Internal Earth
terminal in the base of the housing using a ring crimp terminal to
secure the earth conductor under the earth clamp. The earth
conductor should be at least equal in size and rating to the incoming
power conductors but at least a mini mum of 0.82mm2 / 18AWG in
size.
External earth connections can be made to the M5 earth stud (see
Fig. 4), using a ring crimp terminal to secure the earth conductor
to the earth stud. The external earth conductor should be at least
4mm
2 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.
7.4 Cable Glands, Blanking Elements & Adapters
Ingress Protection
If a high IP (Ingress Protection) rating is required then a suitable
sealing washer must be fitted under the cable glands or blanking
plugs. A minimum ingress protection rating of IP6X must be
maintained for installations in explosive dust atmospheres.
To maintain the ingress protection rating and mode of protection,
the cable entries must be fitted with suitably rated cable entry
and/or blanking devices during installation.
If entries are fitted with adaptors they must be suitably rated for
the application. Fitting of blanking elements into adaptors is not
permitted.
Adapters
The D1x range can be supplied with the following types of adapters:
M20 to ½” NPT
M20 to ¾” NPT
M20 to M25
It is important to note that stopping plugs cannot be fitted onto
adapters, only directly onto the M20 entries.
