Operating Environment Determine the Switch mounting direction and structural Prior to using the Switch in places that are subject to contact with oil, design only after thorough risk assessment. For water, or chemicals, check the effect of those substances on the example, in a structure where the Switch protrudes from Switch. the pendant perimeter, the weight of the pendant itself Some types of oil, water, and chemicals will degrade the sealing could place the Switch into the enable condition and operate the machine. Likewise, in a buried structure capability, which may result in contact failure, defective insulation, where the Switch lies below the surface of the pendant, ground fault, or burning damage. the Switch may not enter the grip condition when pressed and thus fail to stop the machine. Improper Operating Environment • Do not use the Switch in places that are subject to sudden Configure the system so that the machine operates only temperature change. when the Switch is in the enable position. • Do not use the Switch in places that are subject to high temperatures and condensation. • Do not use the Switch in places that are subject to strong vibration. Precautions for Correct Use • Do not use the Switch in places that are subject to direct contact Mounting with machine filings or dust. Use M3 screws and flat washers or spring washers to mount the Switch securely. Use a tightening torque of 0.39 to 0.59 N·m.
