DC Chassis Power Connections

For redundancy, each power input module should be connected to a separate DC source to protect
against line input failure. To connect an Xedge 6280 chassis to a DC power source requires the
following customer-provided components:
• Station battery source(s)
• Voltage measured at the field terminal connector must not be less than -42Vdc.
• Insulated copper wire sized to carry 15A at -48Vdc nominal.
EMC Requirements
The wire pair between the power distribution point and the chassis cabinet must have at least one
twist per inch. If the distribution point and chassis are separated by 5 feet or more, the twisted wire
must extend at least 5 feet from the chassis. The twisted pair wiring must incorporate a shielding
braid (Alpha Wire Corporation number 2172, or equivalent). The shields braid must be electrically
connected to the chassis GND at both ends, at the DC mains entry terminal block GND terminal,
and at a clamp bonded to the chassis metal.
Note

A ferrite toroid must be added to the DC input wires. The DC battery input wires (-48V, -48VRET)
must be wound 6 times (6 turns) around a ferrite toroid (Fair-Rite Products Corporation P/N
2643803802 or equivalent) before the input wires connect to the +V and -V DC input terminals. The
6 turns must be evenly distributed around the toroid and the toroid must be located a maximum of
3 inches from the +V and -V DC input terminals. For redundant power supplies and dual station
battery applications, each pair of DC input wires must be wound around a separate toroid.

Connecting DC input power wiring to the PIM terminals:
First attach terminals to the wire ends by crimping the wire to the #6 terminal lugs provided in the
ACU Terminal Lug Kit (P/N 010K378-001) using a Burndy Electrical Co. Hytool type Y10D. (Call
Burndy customer service at 1-800-346-4175 for ordering information.)
