Additionally there may be significant property damage. 72±0.1 63.3±0.1 13.5±0.1 Two, 3.2-dia.+0.2 0 holes Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. !WARNING Do not wire the Switch or touch any terminal of the Switch while power is being supplied. Doing so may result in electric shock. Always use the Switch in a system that is operated directly by hand. Do not operate the Switch with a mechanical actuator. Insufficient Switch strength may result in damage to the Switch, electric shock, or fire. Design a safe system for using the Switch, based on a risk assessment that takes into account all reasonably foreseeable malfunctions. Prior to using the Switch in places that are subject to contact with oil, water, or chemicals, check the effect of those substances on the Switch. Some types of oil, water, and chemicals will degrade the sealing capability, which may result in contact failure, defective insulation, ground fault, or burning damage. Improper Operating Environment • Do not use the Switch in places that are subject to sudden temperature change. • 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. • Do not use the Switch in places that are subject to direct contact with machine filings or dust. Configure the system so that the machine operates only when the Switch is in the enable position. Precautions for Correct Use Mounting 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. 4-Contact type 44.3±0.1 44.3±0.1 8 9.5±0.1 8 34.5 Four, 2-dia. holes 8 13.5±0.1 8 +0.2 0 39 +0.2 0 Two, 3.2-dia. holes Four, 2-dia. holes +0.2 0 Two, 3.2-dia.+0.2 holes 0 Horizontal mounting type (2-Contact type/4-Contact type) 70.3±0.1 Two, 3.2 +0.2 0 • Use an appropriate wire size (0.5 to 0.75 mm2) for the applied voltage and carry current. • Do not use a #110 tab receptacle. • Wire according to the terminal numbers. Mistaken wiring may damage the Switch and result in fire. • Wire according to the terminal arrangement. • Use good-quality 6:4 (tin:lead) solder. • Use a resin flux cored solder. • Do not use a liquid or chlorine type flux. • Perform soldering within 3 s using a 30-W max. soldering iron (temperature at the tip of the soldering iron: 350°C max.). Insulate with an insulation tube. • Do not move the terminal for at least one minute after soldering. • Do not apply a force that would deform the terminal when wiring. Operating Environment Determine the Switch mounting direction and structural design only after thorough risk assessment. For example, in a structure where the Switch protrudes from the pendant perimeter, the weight of the pendant itself could place the Switch into the enable condition and operate the machine. Likewise, in a buried structure where the Switch lies below the surface of the pendant, the Switch may not enter the grip condition when pressed and thus fail to stop the machine. No-mounting-bracket type 2-Contact type Wiring dia. holes or M3 screw holes Storage • Do not store the Switch in places with hydrogen sulfide or other corrosive gas or sea breeze. • Do not store the Switch in places where the level of dust is high enough to be visible. • Do not store the Switch in direct sunlight. • Do not impose excessive force on the Switch during storage. Otherwise, the Switch may deform. Handling • Do not drop the Switch. Otherwise, the Switch may malfunction. • Do not apply strong vibration or shock to the Switch. Otherwise, the Switch may malfunction or be damaged. Do not contact the Switch with sharp objects. Otherwise, the Switch may be scratched. Scratches on the operating portion of the Switch may result in problems both in appearance and operation.
