Assembling the DC input power wires
Prerequisites
WARNING: 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
1. Strip the insulation from the ends of the DC power wires, exposing approximately 13 mm (0.5 inch)
of copper wire.
WARNING: 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 #2 screwdriver.
WARNING: 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 PSU.
