Dell PowerEdge R750 Installation and Service Manual

Assembling DC input power wires

1. Strip the insulation from the ends of the DC power wires, exposing approximately 13 mm (0.5 inches) of copper wire.
   NOTE:Reversing polarity when connecting DC power wires can permanently damage the power supply or the system.
2. Insert the copper ends into the mating connectors and tighten the captive screws at the top of the mating connector using a Phillips number 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.
3. Rotate the rubber cap clockwise to fix it over the captive screws.
4. Insert the mating connector into the power supply.
