9.
The armouring must fan out to 90 degrees with a 30mm diameter to be clamped properly.
See
Figure 58. Strip back outer sheath of cable exposing the correct length of armouring
to be bent down to achieve this.
10.
Check the inner cable cores can pass through the holes in the top clamp. If the holes are
too small, then replace the top clamp with the larger 22mm diameter option
(667/2/53017/001).
11.
Using pliers bend armouring out to 90 degrees.
See
12.
Repeat for the next cable (up to 4 cables per compression seal).
Compression Seal Blocks
1 off compression seal block is provided directly under the master switch panel for mains,
communications cable etc. In addition, there are another 3 seal blocks provided (12 cable
entries for street cables), see Figure 44. If more cable entries are required use the Plus+ cabinet
seal expansion kit

Extra 8 Cables - 667/1/53065/008.
13.
Replace the top clamp and nuts.
14.
Tighten down the nuts on the top clamp. Tighten each nut a little at a time so that the
force is distributed evenly across the plate. This will minimise any side loads from being
applied to the top clamp. Tighten until the bottom clamp touches the base plate.
15.
Terminate the cables in the cabinet.
16.
Replace the stool door.
Earth Connection
An earth connection is made by sandwiching the cable armouring between the top and bottom clamps.
It is important that the clamping force is applied evenly across the clamp plates so please make sure
that cable armouring does not overlap between cables.
Grease on studs
There should be some grease on each stud, please make sure it is there. If there is no grease then it is very
likely that the nut could seize making it unremovable in the future. If there is no grease then please apply
either carbon grease or copper grease to the stud.
