Installation and Testing
3.9.8 Teleline Shelf Slot 5
The fifth slot of the Teleline shelf is wired direct to the protector block. It appears
as position 5 and 13 on the right hand side of the protector block. Any Positron
Teleline circuit card type can be deployed in slot five and will appear on the
protector block at those locations.
3.10 Installation and Testing
3.10.1 Lightning Arrestor
³
Attaching The Lightning Arrestor to the Cable Shield
1. The insulation around the cable sheath should be stripped only in an area of 4
inches where it is to be clamped to the lightning arrestor. Caution should be
taken not to strip the insulation or cut the cable in any other area.
2. Using a sheath knife, make a 6 cm (2 1/2”) long slit longitudinally in the shield
along the length of the cable. Be careful not to damage the inner poly wrap if
the cable is so equipped.
3. Using a sheath knife, make a 4 cm (1 1/2”) long slit around the shield,
perpendicular to the slit in Step 2. Do not cut all the way around the cable.
This cut would be approximately 2 cm (3/4”) long on each side of the
longitudinal slit created in Step 2. Do this at both ends of the Step 2 slit. Be
careful not to damage any inner poly wrap.
4. Carefully fold these created shield flaps back, sufficiently far to allow for the
base of the cable bond clamp to be placed in the created void.
5. Place the cable clamp base into the created void. If there is no inner poly wrap
on the cable in use, use two layers of vinyl tape to create an insulating blanket
under the clamp.
6. Carefully bend the shield flaps back into place and on top of the bond clamp.
This action captures the base of the bond clamp between the inner poly
insulation and the shield material.
7. Place the outer bond clamp pressure plate and one nut on the stud of the
bond clamp. Then tighten securely.
