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 t wisted-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 4mm2 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 g round 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.
