Required Wires

•One UL 4 AWG, 2 m maximum (stranded) black wire [–(48–60) V DC]

•One UL 4 AWG, 2 m maximum (stranded) red wire (V DC return)

•One UL 4 AWG, 2 m maximum (stranded) green/yellow/green with a yellow stripe wire (safety ground)

Assembling and connecting the safety ground wire

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 is not authorized by Dell is not covered by your warranty. Read and follow all safety instructions that came with the product.

NOTE: It is recommended that you use stranded copper wire type.

1.Strip the insulation from the end of the green or yellow wire (safety ground wire), exposing approximately 4.5 mm (0.175 inch) of copper wire.

2.Using a hand-crimping tool, crimp the ring-tongue terminal to the green or yellow wire.

3.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 and tighten it firmly to the grounding post.
