Installation

Mounting

The Allen-Bradley vacuum contactor is normally fixed mounted (bolted down) in

the enclosure of the controller. There are four (4) mounting holes at the base of

the contactor (Figure 3.1) to secure it to the enclosure. For reversing, autotrans-

former and 2-speed controllers, one contactor may be mounted on top of the

other. There are four (4) threaded mounting holes at the top of the contactor to

accommodate this configuration.

IMPORTANT: The contactor is a bolted assembly and is therefore subject to twisting if fastened to an uneven surface.

The contactor mounting plate has small stand-offs that permit the contactor to be fastened without twisting the frame.

The contactor may not function correctly if it is forced onto an uneven mounting surface.
