Appropriate Tightening Torque
* Apply a tightening torque of 0.78 to 0.88 N·m to three-conduit
• Do not use the Switch submerged in oil or water, or in locations
• Always attach the cover after completing wiring and before using

Changes in Head Mounting Position
By removing the screws on the four corners of the head, the head can
be reset in any of four directions. Make sure that no foreign materials
will penetrate through the head.

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.
