Ensure the frame ground wires are long enough to reach from the shelf connector
panel to the frame ground connection. Use one 1.47 mm (16 AWG) green insulated
wire to connect the
and use another 1.47 mm (16 AWG) green insulated wire to connect the
of TB2 to frame ground.
Make the ground connection, following one of the methods described below,
depending on whether a ground rod is installed:
With ground rod
Solder the frame ground connection to the 4.115 mm (6 AWG) frame ground rod run
vertically on each side of the rack. Two methods are acceptable:
Crimp an appropriate-size spade lug (user-supplied) to the 1.47 mm (16 AWG)
wire, bend the lug around the 4.115 mm (6 AWG) rod, and solder.
Strip enough insulation from the 1.47 mm (16 AWG) wire to permit three
complete turns around the 4.115 mm (6 AWG) rod, and solder.
Note: When soldering, use a 25 watt soldering iron to ensure the
4.115 mm (6 AWG) rod is heated sufficiently to prevent a cold solder
connection.
Without ground rod
Crimp the supplied spade lug to the 1.47 mm (16 AWG) wire, and screw the lug to a
screw hole on the rack. Remove the paint and sand the area around the screw hole
to ensure proper conductivity. Coat the connection with an electrically conductive
antioxidant compound, for example, Kopr-Shield spray.
Crimp the supplied spade lug to the other end of the 1.47 mm (16 AWG) wire, and
connect it to the
