Installation
Mounting e Allen-Bradley vacuum contactor is normally xed mounted (bolted down) in
the enclosure of the controller. ere 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. ere are four (4) threaded mounting holes at the top of the contactor to
accommodate this conguration.
IMPORTANT: e contactor is a bolted assembly and is therefore subject to twisting if fastened to an uneven surface.
e contactor mounting plate has small stand-os that permit the contactor to be fastened without twisting the frame.
e contactor may not function correctly if it is forced onto an uneven mounting surface.
