Upgrade a two-cabinet system with metal cable to Option 11C
5 Install a grounding block in the area of the main cabinet.
Route the grounding wire to the grounding block, then install a ground
wire from the block to the grounding lug in the main cabinet (see
Figure 25 on page 69).
Use #6 AWG (40 Metric) ground wire. For more information about
grounding, refer to the Option 11C Planning and Installation Guide
(553-3021-210) .
Note 1: Grounding methods vary depending on the type of
cross-connect terminal used. You do not always need an NTBK80
grounding block (such as with the Krone Test Jack Frame used in
some countries). Refer to the Option 11C Planning and Installation
Guide (553-3021-210) for more information.
Note 2: Do not install a grounding wire to the existing expansion
cabinet. Install a ground wire when the new expansion cabinet is in
position.
