10 / 12 page D4NS 10 Safety Precautions Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches”. !CAUTION • Do not use the Switch submersed in oil or water or in locations continuously subject to splashes of oil or water. Doing so may result in oil or water entering the Switch. (The IP67 degree of protection of the Switch specifies the amount of water penetration after the Switch is submerged in water for a certain period of time.) • Always attach the cover after completing wiring and before using the Switch. Also, do not turn ON the Switch with the cover open. Doing so may result in electric shock. • Do not switch circuits for two or more standard loads (250 VAC, 3 A). Doing so may adversely affect insulation performance. Stopper Installation Do not use a Switch as a stopper. Be sure to install a stopper as shown in the following illustration to ensure that the base of the Operation Key does not strike the Head, and adjust the stopper to be within the setting zone (0.5 to 3 mm) of the base of the Operation Key. Do not subject the Switch to a shock that exceeds the Switch's shock resistance of 1,000 m/s2. The Switch contacts can be used with either standard loads or microloads. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced. Mounting Method Appropriate Tightening Torque • Loose screws may result in malfunction. Tighten the screws to the specified torques. • When loosening a screw with an electrical screwdriver or similar tool while pressing down on the screw head, do not continue turning the screw past the point where the threads disengage. Doing so may strip the end of the threads. Mounting Holes • Use M4 screws and spring washers to mount the Switch and Operation Key, and tighten the screws to a suitable torque. To ensure safety, use screws that cannot be easily removed or another means to prevent the Switch and Operation Key from easily being removed. • As shown below, two studs with a maximum height of 4.8 mm and a diameter of 4 mm can be provided, the studs inserted into the holes on the bottom of the Switch, and the Switch secured at four locations to increase the mounting strength. • Set the Operation Key so that it is within 1 mm of the center of the key hole. If the Operation Key is offset or at an angle, accelerated wear or breaking may result. • Observe the specified insertion radius for the Operation Key and insert it in a direction perpendicular to the key hole. Head Direction • The rotation of the Switch head may be adjusted to any of the four directions by loosening the head mounting screws at the four corners of the head. Make sure that no foreign materials enter through the head. • Do not insert or remove the Operation Key with the Switch head removed. Doing so may make it impossible to insert the Operation Key. Securing the Door When the door is closed (with the Operation Key inserted), the Operation Key may exceed the set zone because of, for example, the door's own weight, machine vibration, or the door cushion rubber. Secure the door with a stopper so that the Operation Key remains within the set zone. Electric shock may occasionally occur. Do not use metal connectors or metal conduits.
