Be sure that all of the ground connections are without splices and are visible for inspection and
maintenance. Tag all of the ground connections with a sign that reads: Do Not Remove Or
Disconnect.
If you install expansion modules on the base cabinet, attach at least a #10 or #12 insulated, solid
copper wire between the frame ground stud on the expansion module(s) to the frame ground stud
on the base cabinet.
Remember, if spare conductors exist in the cables that run between the stations and the 66M-xx
connector blocks, it is good practice to connect them to earth ground. Doing this may help
prevent them from introducing radio frequency and/or AC interference into the system. Also
remember that it is good practice to disconnect any unused station jacks from the connector
block and ground that wiring to earth ground as well.
