Dell PowerEdge M1000e Enclosure Owner's Manual

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.

CAUTION: When stranded wiring is required, use approved wiring termination, such as closed-loop or spade-type with upturned lugs. These terminations are the appropriate size for the wires and must be double crimped, one on the conductor and one on the insulation.

CAUTION: When installing the unit, the ground connection must always be made first and disconnected last to prevent an energy hazard.

CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
