Cisco IE 3000 Switch Hardware Installation Guide

Appendix B Installation In a Hazardous Environment

Verifying Switch Operation

Obtain these necessary tools and equipment:

• Ratcheting torque flathead screwdriver that exerts up to 15 inch-pounds (in-lb) of pressure

• Ring terminal lug (such as Thomas & Bett part number 10RCR or equivalent)

• Crimping tool (such as Thomas & Bett part number WT2000, ERG-2001, or equivalent)

• 10-gauge copper ground wire (such as Belden part number 9912 or equivalent)

• For DC power connections, use UL- and CSA-rated, style 1007 or 1569 twisted-pair copper

appliance wiring material (AWM) wire (such as Belden part number 9318).

• Wire-stripping tools for stripping 10- and 18-gauge wires

Grounding the Switch

To ground the switch to earth ground by using the ground screw, follow these steps. Make sure to follow

any grounding requirements at your site.

Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the

absence of a suitably installed ground conductor. Contact the appropriate electrical inspection

authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning

This equipment is intended to be grounded to comply with emission and immunity requirements.

Ensure that the switch functional ground lug is connected to earth ground during normal use.

Statement 1064

Note Use at least a 4mm

conductor to connect to the external grounding screw.

Step 1 Use a standard Phillips screwdriver or a ratcheting torque flathead screwdriver with a Phillips head to

remove the ground screw from the front panel of the switch. Store the ground screw for later use.

Caution To make sure that the equipment is reliably connected to earth ground, follow the grounding procedure

instructions, and use a UL-listed ring terminal lug suitable for number 10-to-12 AWG wire, such as

Thomas & Bett part number 10RCR or equivalent.

Step 2 Use a wire-stripping tool to strip the 10- gauge wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm). See

Figure B-9.
