DC Power Supply Wiring Instructions
The following image shows the wiring configuration for a 48 VDC power supply in a
negative ground system application. For positive ground system applications remove
the chassis ground shorting jumper and connect it between the positive terminal and
the chassis ground terminal. Alternatively, the chassis grounding jumper can be
eliminated and the chassis ground connected at the power source.
NOTE
Incorrect wiring will result in chassis malfunction. The IE-MediaChassis/2 (DC) is
compliant with Isolated Grounding Plane practices. The POSITIVE and NEGATIVE
terminals are isolated from chassis ground and must have a ground reference at the
power-sourcing equipment.
This equipment is designed to permit the connection of the grounded conductor of
the DC supply circuit to the grounded conductor at the equipment. If this
connection is made, all of the following conditions must be met:
1.
This equipment shall be connected directly to the DC supply system
grounded electrode conductor or to a bonding jumper from a grounded
terminal bar or bus to which the DC supply system grounding electrode
conductor is connected.
2.
This equipment shall be located in the same immediate area (such as,
adjacent cabinets) as any other equipment that has a connection between
the grounded conductor of the same DC supply circuit and the grounding
conductor, and also the point of grounding of the DC system. The DC
system shall not be grounded elsewhere.
