10.7 Grounding System Terminal Access Procedure
Fiber optic cables with metallic strength members or shields are grounded to a common
grounding system. The grounding system is designed to allow the metallic elements of each
cable to be isolated for connection of cable locating equipment. The grounding system terminals
may be accessed through a small cover located on the side of the cabinet. Use the following
procedure to access and isolate the metallic elements of individual cables:
1. Locate the small hinged access cover on the side of the cabinet as shown in
2. Use the 216B tool to remove the screw that secures the access cover in the closed position.
3. Open the cover and locate the grounding stud that corresponds to the cable to be located.
4. Remove the stud nut and disconnect the cable so that it is not touching the copper bus bar
assembly.
5. Attach cable detection equipment to the isolated grounding cable and complete the cable
location procedure.
6. When finished locating cables, reconnect the cable terminal to the grounding stud.
7. Tighten the grounding stud nut to 30 to 35 lbs force-inches. (3.4 to 4.0 Nm) of torque.
8. Close and secure grounding block access cover.
Note:
A designation label is provided on the access cover for identifying cables.
Warning:
The grounding cables are connected to cabinet ground through the copper grounding
blocks. Failure to properly tighten the nut on each individual cable grounding stud could result
in improper grounding of the cable and result in performance or safety issues.
