Installing the 7800 N+1 Patch Panel
6.3
Grounding the Equipment Chassis
As a standard safety practice, the chassis of 7800 N+1 patch panel must be properly grounded to
protect against any contact with an electrical fault condition. It is recommended that the chassis be
connected to earth ground. When the 7800 N+1 patch panel is installed in an equipment rack, connect
the ground wire between the ground lug of the patch panel and the equipment rack ground bar.
Guidelines
•
Use 10 AWG (minimum) stranded ground wire.
•
Terminate equipment side of ground wire with a #10 ring terminal.
•
Keep the length of the ground wire as short as possible.
•
Do NOT daisy chain the ground between equipment. Use a ground bus bar.
•
Do not over tighten ground lug connections.
To connect to the 7800 N+1 Patch Panel to ground:
1.
Connect one end of a ground wire to the ground lug of the 7800 N+1 Patch Panel. See

on
page
51.
2.
Connect the other end of the ground wire to a ground bar of the equipment rack.If the 7800 N+1
Patch Panel is not installed in an equipment rack, connect the ground wire to earth ground.
3.
Verify that the resistance of the ground path is less than 0.5 ohms.
