Indication and Meaning for Safe Use Precautions for Correct Use The Switch contacts can be used with either standard loads or Precautions Supplementary comments on what to do microloads. Once the contacts have been used to switch a load, or avoid doing, to use the product safely. for Safe Use however, they cannot be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact Supplementary comments on what to do Precautions reliability for smaller loads may be reduced. or avoid doing, to prevent failure to for Correct operate, or undesirable effect on product Use Appropriate Tightening Torque performance. Be sure to tighten each screw of the D4F properly, otherwise the D4F may soon malfunction . Precautions for Safe Use No. Type Appropriate tightening torque • Do not use more than one D4F side-by-side. 1 Lever mounting screw (M5) 2.4 to 2.8 N·m • Do not switch circuits for two or more standard loads (125 VAC, 1 A). Doing so may adversely affect insulation performance. 2 Body mounting screw (M4) 1.18 to 1.37 N·m Handling of Cables • Cables cannot be flexed repeatedly. • The cable is fixed with sealing materials on the bottom of the switch. When excessive force may be imposed on the cable, fasten 1 the cable with a fixing unit at a distance of 50 mm from the bottom of the switch as shown. 2 • Do not pull or press the cable at an excessive force (50 N max.). • When bending the cable, secure the cable with more than 45 mm bending radius so as not to cause damage to the insulator or sheath of the cable. Doing so may result in current leakage or burning. Mounting Use two M4 screws and washers to mount the D4F securely. The D4F can be mounted more securely with proper tightening torque. Mounting Holes (Unit: mm) Two, 4.2-dia. or M4 screw hole Bending radius: 50 mm 45 mm min. 20±0.1 Fixing unit Changing the Lever Angle • When wiring, be sure to prevent penetration of a liquid such as water or oil through the cable end. • Unfasten the screw that holds the lever to set the position of the lever at any angle through 360° (in steps of 9°). • After unfastening the screws that hold the lever, mount the lever Operating Environment the other way (normal side or reverse side).
