Next steps
1. If you have unlatched the cable management arm, relatch it. For information about the cable management arm, see the
system’s rack documentation at Dell.com/XCSeriesmanuals.
2. Connect the power cable to the PSU, and plug the cable into a power outlet.
CAUTION: When connecting the power cable to the PSU, secure the cable to the PSU with the strap.
NOTE: When installing, hot swapping, or hot adding a new PSU, wait for 15 seconds for the system to recognize the
PSU and determine its status. The PSU redundancy may not occur until discovery is complete. Wait until the new PSU is
discovered and enabled before you remove the other PSU. The PSU status indicator turns green to signify that the PSU
is functioning properly.
Wiring instructions for a DC power supply unit
Your system supports up to two –(48–60) V DC power supply units (PSUs).
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 EMC 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 90ºC 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.
