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
use sandpaper or a file to remove oxidation 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
terminals on TB1 and TB2
(Figure 25).
If the power is not to be connected immediately, replace the
protective covers on the terminal blocks.
