IMPORTANT
Save these instructions for future use. This publication
does not include all specifications, dimensions, or special
installation considerations.
ATTENTION: To avoid electrical shock and unintended operation
of equipment, disconnect all power to the safety limit switch and
the controlled equipment before you replace or adjust the safety
limit switch.
Improper selection or installation of the devices affects the
integrity of the safety systems and can result in personnel injury
or death, property damage, or economic loss.
Comply with ISO 14119 including selection, accessibility to the
installation, arrangement and fastening, possible substitute
actuation, access to the escape release, motivation to defeat, and
actuation mode.
Use management controls, working procedures, training and
additional procedures to minimize the motivation to defeat.
Comply with ISO 13857 and ISO 13855 for guard openings and
minimum (safe) distances.
IMPORTANT
• Before installation in a safety application, perform a risk
assessment to determine whether the specifications of this
device are suitable for the foreseeable operational and
environmental characteristics of the machine that the
device controls.
• Only the N.C. set of contacts are considered safety
contacts.
• Follow all applicable standards for the application when you
deploy these safety limit switches.
• Follow operation specifications.
• Place the actuator beyond the point where direct opening
action occurs.
• Do not use these devices to control a motor directly.

Installation
IMPORTANT
Installation of Allen-Bradley® Guardmaster® products must
be in accordance with local and/or national codes.
Servicing energized industrial control equipment can be
hazardous if not in accordance with recommended safety
procedures.
EN ISO 14119 replaces EN 1088 as the harmonized standard
for interlocking devices associated with guards.
See publication SAFETY-SR001.

Actuation Guidelines
x = 2 (2 m [6.6 ft]), 5 (5 m [16.4 ft]), or 10 (10 m [32.8 ft]) for standard cable lengths.
For other cable lengths, contact your local Allen-Bradley distributor or Rockwell
Automation sales office.
The method of actuation and over travel affects the service life of the safety limit
switch. To maximize the service life, we recommended that you provide an
actuator with a 30° pressure angle and a surface hardness of Rc-45 (max).

These devices require little maintenance, but we recommend routine visual
inspection to help prevent the accumulation of foreign debris on the exterior
actuators and rollers. Do not remove the operator head.
