Mounting instructions
Mounting: Slide the coupling on the shaft ends to the proper axial position.
Using a torque wrench, tighten the clamp screws to the correct tightening torque as indicated (in the table page 12)
CAUTION! Both clamping hubs have different screws and different tighte­ning torques.
Dismounting: Simply loosen the clamp screw I1, I2 and remove the safety coupling.
Emergency cut off: The axial path of the actuation ring activates the mechanical switch or the proximity sensor .
CAUTION! Upon assembly, it is absolutely necessary to test the function of the switch 100%
