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 6 AWG frame ground
rod run vertically on each side of the rack. Use one of the following
methods for connecting the wire from pin 6 of the DB9 connector
to the 6 AWG rod.
• Crimp an appropriate-size spade lug to the ground wire from
the DB9 connector, bend the lug around the 6 AWG rod, and
solder.
• Strip enough insulation from the ground wire from the DB9
connector to permit three complete turns around the 6 AWG
rod, and solder.
Note:
When soldering, use a 25 watt soldering iron to ensure the
6 AWG rod is heated sufficiently, to prevent a cold solder connec-
tion.
Without ground rod
Crimp an appropriate-sized spade lug to the wire from pin 6 of the
DB9 connector, and secure the lug to a screw hole on the rack.
Remove the paint, and sand the area around the screw hole, to
ensure proper conductivity.
