Before connecting or disconnecting ground or power wires to the chassis, ensure that power is 
removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel 
board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch 
handle of the circuit breaker in the OFF position. Statement 140

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

To make sure that the equipment is reliably connected to earth ground, follow the grounding procedure 
instructions, and use a UL-listed lug suitable for 6-AWG wire and two M5 screws.

Obtain these necessary tools and equipment:

Ratcheting torque screwdriver with a Phillips head that exerts up to 15 pound force-inches (lbf in.) 
or 240 ounce force-inches (ozf in.) of pressure

Panduit crimping tool with optional controlled cycle mechanism

18-gauge copper ground wire (insulated or noninsulated)

Four leads of 18-gauge copper wire

Wire-stripping tool for stripping 18-gauge wire

To install the DC grounding leads on the DC power supply, follow these instructions.

The DC power supply ships with the DC power supply ground lugs, star washers, and nut attached to the 
grounding stud on the DC power supply. 

Locate the grounding stud on the DC power supply. 

Remove the nut, ground lug, star washer, and the second ground lug and star washer from the grounding 
stud.
