DC Power Supply Connection
Connecting a DC Cable Harness to the Chassis Power Supply
When plugging in the cable, insert the connector end of the cable harness into the power supply
connector until it clicks firmly into place. This is an indication that the connector is secure and properly
seated. Secure the screws.
Connecting a DC Cable Harness to the DC Power Source
The other end of the cable harness is bare. Users must assemble and connect this end to the DC power
source or to a cable coming from the power source. In addition to following the important guidelines
listed below, be sure to consult manufacturer specifications for the DC power source before starting.
• Connect the power supply to a reliably grounded -24V or -48V DC SELV source.
• Use common DC return connections for the DC power supplies. The DC return terminal conductor
should be connected to the equipment frame.
• The branch circuit overcurrent protection must be rated 15A.
• Use two 12 AWG copper conductors.
• A readily accessible disconnect device that is suitably approved and rated shall be incorporated in
the field wiring.
CAUTION: Installation of a DC cable that is more than 3 meters in length is
subject to LOCAL CODES and AUTHORITIES. Please contact your electrician and
the Local AHJ (Authority Having Jurisdiction) to follow the Electrical Codes
before use of proper installation methods.
