Wiring the power cables

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.

The DC power supply module must be hard-wired to a DC power source in your environment by a qualified electrician. To wire your DC power supply module to a DC power source:

1.Make sure that the power switch is in the OFF position, and the power supply module is turned off.

2.Connect the open terminal (bare wire ends) to an appropriate DC power source. As specified in the following table:

Connect each wire on power cable to the matching wire or terminal on DC power source.

Each wire on the power cable is labeled with information for easy identification.
