Wiring instructions for a DC power supply unit

Your system supports up to two –(48–60) V DC power supply units (PSUs).
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.
CAUTION: Wire the unit with copper only, unless otherwise specified, use only 10 American Wire Gauge (AWG)
wire rated minimum 90 ºC for source and return. Protect the –(48–60) V DC (1 wire) with a branch circuit
over-current protection rated 50 A for DC with a high interrupt current rating.
CAUTION: Connect the equipment to a –(48–60) V DC supply source that is electrically isolated from the AC
source (reliably grounded –(48–60) V DC SELV source). Ensure that the –(48–60) V DC source is efficiently
secured to earth (ground).
NOTE: A readily accessible disconnect device that is suitably approved and rated shall be incorporated in the field wiring.
