DC Power Supply Modules

A 2700 W DC power supply module requires –(48–60) V DC input from a DC power source.

Wiring Instructions For A DC Power Supply

This document describes the requirements and wiring instructions for a –48 V DC power wire and safety ground wire for systems equipped with a –48 V DC supply.

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.

WARNING: An energy hazard will exist if the safety ground cable is omitted or disconnected.

WARNING: The system chassis must be positively grounded to the rack cabinet frame. Do not attempt to connect power to the system until grounding cables are connected.

CAUTION: A qualified electrician must perform all connections to DC power and safety grounds. The system must be safety grounded at the cabinet frame. All electrical wiring must comply with applicable local or national codes and practices.

CAUTION: This equipment is designed to permit the connection of the earthed conductor of the DC supply circuit to the earthing conductor on the equipment. See the installation instructions. If this connection is made, all of the following conditions must be met.

•This equipment must be connected directly to the DC supply system earthing electrode conductor or to a bonding jumper from an earthing terminal bar or bus to which the DC supply system earthing electrode conductor is connected.

•This equipment must be located in the same immediate area (such as, adjacent cabinets) as any other equipment that has a connection between the earthed conductor of the same DC supply circuit and the earthing conductor, and also the point of earthing of the DC system. The DC system must not be earthed elsewhere.

•The DC supply source must be located within the same premises as this equipment.

•The earthed circuit conductor between the DC power source and the earthing electrode conductor must not be connected to switching or disconnecting devices.

Precaution Statements

This product is intended for restricted access locations (dedicated equipment rooms, equipment closet, or the like) in accordance with the National Electrical Code, American National Standards Institute (ANSI)/National Fire Protection Association (NFPA) 70.

CAUTION: Wire the unit with copper only. Unless otherwise specified, use only 4 American Wire Gauge (AWG) wire rated minimum 90 ºC (194 ºF) for source and return. Protect the –(48–60) V DC (1 wire) with a branch circuit overcurrent protection rated 100 A for DC with a high interrupt current rating.

Connect the equipment to a –48 V DC supply source that is electrically isolated from the AC source (reliably grounded 48 V DC SELV source). Ensure that the –48 V DC source is secured to earth (ground).

NOTE: A readily accessible disconnect device that is suitably approved and rated must be incorporated in the field wiring.
