Chassis Grounding
Chassis Grounding
Chassis grounding is provided through the power cable, which uses a standard grounding plug. The
chassis is also equipped with two multi 4 x 0.7 screw terminals for chassis grounding. The accessory kit
contains a crimp-type ground lug that attaches to the two screw terminals. For more information, refer
to the
“Installing the Ground Connection” section on page 3-11.
