■ Always tighten each part of the safety switch to the tightening torque recommended in the product specifications. Tightening any part excessively, might damage the threads and/or other parts ■ Mount the dog so that no force is directly applied to the actuator in the free state ■ Do not use silicone adhesive or silicone grease. Doing so might result in faulty electrical contact ■ Do not do wiring work with the power ON. Doing so might cause an electrical shock or cause the device to operate unexpectedly ■ Do not apply excessive force (5 times larger than the O.F.) to the actuator when it...
