Assembling 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
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 power
supply.
