Xedge 6640 AC Power Connections

Note
IMPORTANT! Before making AC power connections, ensure that the chassis is the Xedge 6640 AC model.
The upper rear panel of the Xedge 6640 chassis contains connectors for the required power source.
There are two connectors for two AC power cables. The upper connector feeds AC to the power
supplies installed in slots A and B and the lower connector feeds AC to the power supplies installed
in slots C and D. For power source redundancy, connect these cables to independent AC mains. Two
AC power cords (US 120 VAC) are supplied with each Xedge 6640 chassis. Export AC power cords
are optional. The following table provides ordering information for optional AC power cords:

Xedge 6645 DC Power Connections

Note
IMPORTANT! Before making DC power connections, ensure that the chassis is the Xedge 6645 DC model.
EMC Requirements
To comply with 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
For contact information see Alpha Wire Corporation's website at www.alphawire.com.
Also for EMC requirements, 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.
