Rockwell Automation 1502 400 Amp Medium Voltage Contactor (Series D) - Manual (Page 20)

3-2 Installation
1502-UM050D-EN-P – June 2013
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, an optional control panel with connecting
wire harness is available from Rockwell Automation.
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
ft/lbs. (292 N/m) to secure the connection.
Connect outgoing power to the load side terminals halfway down the rear of
the contactor. Use 3/8-in. (10 mm) bolts torqued to 20 ft/lbs. (292 N/m) to
secure the connection.
For mechanically latched contactors, ensure the manual trip button in the
cabinet door is in line with the trip lever on the contactor.
