2.5.2 Using Cable Ties
If at least 10 m (33 ft) of outside
plant cable is routed within an
environmentally controlled building
where temperature fluctuation is
minimal, securing the cable sheath is
adequate strain-relief.
Step 1:
Attach the cable to the
strain-relief bracket with
cable ties in two places as
shown in Figure 6.
Step 2:
Allow room on the bracket
to strain-relieve the cable
strength member. Proceed to Section 2.6.
2.6 Strain-relieving the Strength Member
If using the UCC for strain-relief, it is not necessary to strain-relieve the strength member. You
may skip this section.
Step 1:
Install the U-shaped washer and the flat washer on the strain-relief bracket using the
supplied Phillips-head machine screw (Figure 6).
Step 2:
Place the yarn, if present, and the central member between the U-shaped washer
and the flat washer.
Step 3:
Wrap yarn around the screw and under U-shaped washer in a clockwise direction.
Step 4:
Tighten the nut.
Step 5:
Trim off the excess yarn and central member.
2.7 Grounding Armored Cable
If cable you are using is armored, a grounding kit (p/n FDC-CAbLE-GRND, purchased
separately) is required to ground each armored cable. Follow the instructions provided with the
grounding kit.
Step 1:
Attach the other end of the ground wire to the equipment rack. The equipment rack
must be grounded to the primary building ground.
Step 2:
Remove the paint from the frame at the grounding location to ensure metal-to-
metal contact. It is recommended to use an antioxidant on the bare metal to prevent
corrosion.
Step 3:
Or, attach the other end of the ground wire to a rack-mounted grounding bus bar,
which is grounded to the primary building ground.
