3. Install barrier. Route the cable assemblies through the
rectangular holes in the barrier [3]. Secure the barrier
to the side of the “Z” rail with 10-32 x
7 / 16 " thread-
forming screws [23], as shown in Figure 7 and tighten
to 22 in-lb.
4. Mounting plate. Route the cable assemblies through
the oblong slot in the mounting plate [5]. Secure the
mounting plate to the interior “Z” rail with
10-32 x
7 / 16 " thread-forming screws [23], as shown in
Figure 8 and tighten to 22 in-lb.
5. Mount the TVSS unit. Remove the two screws securing
the plastic cover to the TVSS unit and lift off the
cover. Save the screws for later reinstallation. Mount
the unit to the mounting plate with six 10-32 x
7 / 16 "
thread-forming screws [23] and tighten to 22 in-lb.
6. Make cable connections to the TVSS. Trim the cable
assemblies to the minimum required and strip 1 / 2
inch from the end of the cable. Connect the cable
assemblies to the lugs provided in the TVSS unit and
tighten the lug screws to 110 in-lb. Insure that the A
location is connected to the top lug, the B location (if
required) to the middle lug, and the C location to the
bottom lug, as shown in Figure 9.
a. Install ground (and neutral cable if required).
Measure the length required for the ground and
neutral cables and cut from the cable [1]. Strip
1 / 2
inch from the end of the cable and connect to the
TVSS ground and neutral lugs and panel lugs, as
shown in Figure 9. Tighten the lug screws to 110
in-lb. Reinstall the plastic cover on the TVSS.
b. Install the cable connections from the circuit
breaker to the TVSS. Trim the cable [21] to the
length required and strip the ends as required.
Connect the cable to the appropriate connection
