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.
