Grounding Cable and Lug Specifications for an EX4600 Switch

For installations that require a separate grounding conductor to the chassis, the switch must be
adequately grounded before power is connected to ensure proper operation and to meet safety and
electromagnetic interference (EMI) requirements. To ground an EX4600 switch, connect a grounding
cable to earth ground and then attach it to the chassis grounding points.
WARNING: The switch is pluggable type A equipment installed in a restricted-access
location. It has a separate protective earthing terminal provided on the chassis in
addition to the grounding pin of the power supply cord. This separate protective
earthing terminal must be permanently connected to earth ground for installations that
require a separate grounding conductor to the chassis.
CAUTION: Before switch installation begins, a licensed electrician must attach a cable
lug to the grounding cables that you supply. See

switch.
Before connecting the switch to earth ground, review the following information:
• A protective earthing terminal bracket is provided in the accessory kit for connecting the switch to
earth ground. This L-shaped bracket attaches to the side of the EX4600 chassis through the
mounting bracket, providing a protective earthing terminal for the switch.
• The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided).. The grounding
lug should accommodates 14–10 AWG (2–5.3 mm²) stranded wire.
