DANGER
• The machine on which the GL-T11R is to be installed must be
susceptible to an emergency stop at all operating points during its operation cycle. Do not use the GL-T11R for machines
with irregular stop times.
• Do not use the GL-T11R for power presses equipped with fullrevolution clutches.
• The GL-T11R cannot be used as a PSDI because it does not
fulfill the requirements of OSHA 1910.217(h). Refer to OSHA
1910.217 for the PSDI mode.
• Do not use the GL-T11R to control (stop forward motion, etc.)
trains, cars and other transportation vehicles, aircraft, equipment for use in space, medical devices, or nuclear power generation systems.
■ Circuit design and wiring
• Always turn off the power to the GL-T11R when performing
electrical wiring.
• You must fulfill the electrical standards and regulations in the
country or region in which the GL-T11R is being used when
you perform the electrical wiring.
