Assembling and Connecting the Safety Ground Wire for DC Power Supply

WARNING: For equipment using –(48–60) V DC power supplies, a qualified electrician must perform all connections

to DC power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself. All

electrical wiring must comply with applicable local or national codes and practices. Damage due to servicing that

Dell Networking did not authorize is not covered by your warranty.

Strip the insulation from the end of the green/yellow wire, exposing approximately 4.5 mm (0.175 inch) of copper

wire.

Using a hand-crimping tool (Tyco Electronics, 58433-3 or equivalent), crimp the ring-tongue terminal (Jeeson

Terminals Inc., R5-4SA or equivalent) to the green/yellow wire (safety ground wire).

Connect the safety ground wire to the grounding post on the back of the system using a #6–32 nut equipped with a

locking washer.
