Dell PowerEdge R730 Owner's Manual

Assembling the DC input power wires

Prerequisites

NOTE: For equipment using –(48–60) V DC power supply units (PSUs), 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.

Steps

Strip the insulation from the ends of the DC power wires, exposing approximately 13 mm (0.5 inch) of copper wire.
NOTE: Reversing polarity when connecting DC power wires can permanently damage the power supply or the system.
Insert the copper ends into the mating connectors and tighten the captive screws at the top of the mating connector by using a Phillips #2 screwdriver.
NOTE: To protect the power supply from electrostatic discharge, the captive screws must be covered with the rubber cap before inserting the mating connector into the power supply.
Rotate the rubber cap clockwise to fix it over the captive screws.
Insert the mating connector into the PSU.
