Internal Wiring Guidelines – All cables and wires must be run as
closely to the panel as possible. AC, DC and control wires should be
stacked and run as shown in Figure B.8.

AC Power

When the AC power leads must leave the ground plane of the
mounting panel to make connection to elevated device terminals, a
ground wire should be run with that wire bundle. Refer to Figures
B.10 and B.11 for typical panel electrical layouts.

Wiring the AC Line Filter – The line filter is connected in series
from the AC supply line to the AC line inductor to the input
terminals in the Drive as shown in Figure B.9.

AC power wiring from the electrical cabinet power entry to the line
filter must be:

D As short as possible.
D Separated from any other wiring to prevent coupling high

frequency noise back to the filtered leads.

D Run as close to the ground plane as possible.
