Handling of Cables
Operating Environment
• Do not use more than one D4F side-by-side.
• Do not switch circuits for two or more standard loads (250 VAC,
• Cables cannot be flexed repeatedly.
• The cable is fixed with sealing materials on the bottom of the
• 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
• When wiring, be sure to prevent penetration of a liquid such as
• Do not use the Switch submersed in oil or water or in locations
3 A). Doing so may adversely affect insulation performance.

the cable with a fixing unit at a distance of 50 mm from the bottom
of the switch as shown.

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.)

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.
Appropriate Tightening Torque
Be sure to tighten each screw of the D4F properly, otherwise the D4F
may soon malfunction
Mounting
Use two M4 screws and washers to mount the D4F securely. The D4F
can be mounted more securely with proper tightening torque.
