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.

Strip the insulation from the end of the green/yellow wire (safety ground wire), exposing approximately 4.5 mm (0.175 inch) of copper wire.
Using a hand-crimping tool (Tyco Electronics 1490749-1, Upper Die 1490414-2, and Lower Die 1-1490413-6), crimp the ring-tongue terminal (Amp/Tyco PN 33115-1) to the green/yellow wire.
Connect the safety ground wire to the grounding post on the back of the system using a #5/16 nut equipped with a locking washer. The nut must be torqued to 16 in lbs (1.8 N-m) to ensure proper ground wire retention.
