Mounting
Precautions for Safe Use
Use four M5 screws with washers to mount the standard model. Be
• Do not use the Switch submerged 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 interior. (The IP67 degree
of protection specification for the Switch refers to water penetration
while the Switch is submersed in water for a specified 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.
sure to apply the proper torque to tighten each screw. The 3-conduit
models can be mounted more securely by using the four screws plus
two 5−0.105 mm diameter studs, each of which has a maximum height
of 4.8 mm as shown below.

Changes in Actuator Mounting Position
• To change the angle of the lever, loosen the Allen-head bolts on
the side of the lever.
• The operating position indicator plate * has protruding parts which
engage with the lever, thus allowing changes to the lever position
by 90°.
(5)
(2)
• The back of the operating position indicator plate * has no
protruding parts. If this plate is turned over and attached, any angle
within a 360° range can be set. Do not turn over the plate, however,
when using the D4B-@N as a switch with a certified direct opening
mechanism. For an SUVA- or BIA-certified application, make sure
that the lever engages with the operating position indicator plate
securely so that the lever will not slip.
