Electrical Connections A wire harness connects the control wiring to the contactor from the low voltage
control panel. The harness connects to a wire plug on the lower left side of the
contactor. If the contactor is supplied as an OEM component for installation in a
custom application, the following two control options and a connecting wire
harness are available from Rockwell Automation.
• IntelliVAC and IntelliVAC Plus control modules
• Electromechanical control panel (for latch contactors only)
Connect incoming power to the line side terminals at the top, rear of the
contactor near the control fuse clips. Use 3/8 in. (10 mm) bolts torqued to
20 lb
