3.5 AC Input Wiring
All KDC models require 3 phase AC input. A neutral
connection is not available, as the KDC only requires a
delta input. If only three-phase Wye AC power is available,
verify the correct Line-to-Line voltage and connect only the
phase wires.
The Safety Ground connection MUST be made to the stud
marked with the earth ground symbol.
The AC input wires must be terminated with ring lugs (AC
input stud size is ¼”-20 thread, M4 metric) of at least ¼” (7
mm) diameter. See Figure 3-3.
Before attaching wires to line input terminals, wires must
pass-thru strain relief on the safety cover. Always install the
AC input safety cover and strain relief provided with the
unit. The ground wire should be longer than the three
power phase wires by at least 1 inch.
3.5.1 EMI Toroid Installation
– 400V Models
To meet CE Mark conducted emissions, models with 400V AC input must have the supplied
ferrite toroid installed on the AC input wiring as shown. Loop the three phase conductors through
the supplied toroid 4 times (4 turns). This means they loop around the outside of the toroid three
times. This should be done before passing the AC input wires through the safety cover strain relief
and attached them to the AC input terminal studs on the rear of the KDC unit.
