Chassis Ground Wiring
To make sure that the equipment is connected to earth ground, use the following instructions
to prepare the ground wire and make the connection. Ground wire is not provided. The
length of the ground wire depends on the location of the router and proximity to the proper
grounding facilities.
Making the Ground Connection
Tools and hardware required:
• wire stripper
• wire cutter
• crimping tool
• torque driver for hex nut
• M4 ring lug
• minimum #18 AWG wire (green/yellow)
Caution: The 7705 SAR-8 chassis ground stud located on the right-hand side mounting
bracket must be a single-purpose permanent connection to the earth (building) ground point.
Therefore, the connection requires its own washers and nut.
Notes:
• When wiring the unit, the chassis ground connection must always be made first and
disconnected last.
• All bare conductors must be coated with an appropriate antioxidant compound before
crimp connections are made. All unplated connectors, braided strap, and bus bars must
be brought to a bright finish and then coated with an antioxidant before connecting them.
• All surfaces that are used for intentionally grounding the 7705 SAR-8 must be brought to
a bright finish, and an antioxidant solution must be applied to the surfaces being joined.
