Principles, Standards, and Implementation

Operating specifications must be followed. Actuators should
be displaced beyond the point where direct opening action
occurs. If adjustable actuators become loose they may defeat
the direct opening action feature of the limit switch. These
devices are not to be used to directly control a motor.

ATTENTION: To avoid electrical shock and unintended

operation of equipment, disconnect all
power to the limit switch and the controlled
equipment before proceeding with any
repair or adjustment of the limit switch.

IMPORTANT: Installation of Allen-Bradley limit switches should be in

accordance with local and/or national codes. Servicing
energized industrial control equipment can be hazarous if
not in accordance to recommended safety procedures.
