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.

(a) Termination numbers may differ if the controls are CH531 or a Tracer AdaptiView™ controls upgrade.
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
item 13 on Figure 4, p. 13
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.
