Power Termination Procedure
(AI365 Rev 5 – 01Mar16)
6)
Remove the internal earth ring from the rear shell sub
assembly by backing off the 2 grub screws on the flats. If
internal earthing is not required, the internal earth ring
assembly along with the fixing grub screws should be
discarded.
7)
Crimp the lugs or contacts onto the conductors
(excluding internal earth wire if being used) using
suitable crimp tool. (Hawke recommend Elpress crimp
tools). Contact sizes of 185mm² and larger should be
adjacently double crimped as shown.
8)
Feed the conductors through the rear shell assembly and
screw this onto the cable gland entry thread ensuring
the sealing washer is present.
9)
Measure the distance from the front of the rear shell to
the end of the crimp lug (50 – 240mm²) or contact (300 -
630mm²). It should be as shown. If not, remove the rear
shell and add or remove the spacer washers supplied to
get the required length. At least 1 washer must be
present to maintain IP rating.
Internal earth procedure (skip to step 13 if not used or
you have single phase connector).
10)
Slide the internal earth ring down over the conductors
with the lug going over the bare earth wire.
11)
Position the internal earth ring inside the rear shell and
tighten the grub screws into the groove on the earth
ring. Excessive force could distort rear shell.
