Black Box LMC5203A, LMC5208A-R2 manual Wiring Instruction Guidelines for DC Module in 2DC and Acdc

7.Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on over current protection and supply wiring.

8.Reliable Grounding - Reliable grounding of Rackmounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g., use of power strips).

9.All AC and DC versions are intended for use in a Restricted Access Location (RAL).

Wiring Instruction Guidelines for DC Module in 2DC and ACDC

1.Connection of a suitable grounding conductor to the grounding terminal at each power supply module (a minimum 14AWG copper conductor should be suitable based on a 15A circuit breaker requirement).

2.Connection of suitable supply wiring to the plus and minus terminals at each power supply module (a minimum 14AWG copper conductors is considered suitable based on the 11A input maximum). The input terminal block at the power supply module is suitable for 22-14 AWG copper wire.

3.A suitable listed circuit breaker shall be provided in the building installation as the unit's disconnect device. The branch circuit rating (i.e. minimum 15A listed circuit breaker, etc.).

DC Power Supply Module Wiring Instructions

The following diagram shows the wiring configuration for a -48 VDC power supply module for the 20-Slot Rackmount Chassis 2DC and ACDC.

NOTE

The chassis is protected against incorrect wiring configurations. When wired incorrectly, the

chassis will not function, but no damage will occur.
