Input Power and Control Wiring
38 AFDK-SVU01C-EN
Standard Control Wiring
WARNING
Hazardous Voltage with Improper
Grounding!
The motor controller has a chassis ground that MUST
be connected to an earth ground. You MUST follow
requirements for field wiring installation and grounding
as described in NEC and your local/state electrical
codes. Hazardous voltage due to improperly grounded
electrical components could result in death or serious
injury.
Table 18 indicates the typical control wiring for AFDK
installation. Four knockouts have been provided on the left
side of the AFDK enclosure for control and communication
wires. For exact locations, refer to
Figure 7, p. 17 and
Figure 8, p. 18 for Frame 3 units and refer to Figure 9, p. 19
and Figure 10, p. 20 for Frame 4 units.

Control wiring should be terminated at the terminal block
provided. The location of the control terminal block is
called out as item 13 on
Figure 1, p. 9 for Frame 3 units and
item 13 on Figure 4, p. 13 for Frame 4 units. Figure 20,
p. 39 shows an expanded view of the terminal block
provided for control wiring. Field-installed control wiring
should be routed so that it is segregated from factory
installed wiring, unless the conductors of both circuits will
be insulated for the maximum voltage of either circuit.
