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.
