Precautions
If the D4B-
circuit for prevention of injury, use the D4B- N model that has an
NC contact equipped with a force-separation mechanism, and
make sure that the D4B-
N operates in the positive mode.
Also, secure the D4B-
N with screws or equivalent parts that
are tightened in a single direction so that the D4B-
easily removed. Then provide a protection cover for the D4B-
and post a warning label near the D4B-

In order to protect the D4B-
circuiting, connect a fuse breaking a current 1.5 to 2 times higher
than the rated current in parallel with the D4B-
N from damage due to short-
N.
If an application satisfying EN standards is to employ the D4BL,
apply the 10-A gI or gG fuse approved by IEC269.
Do not apply the D4B-

MOUNTING
Use four M5 screws with washers to mount the standard model.
Be sure to apply the proper torque to tighten each screw. The

Changes in Actuator Mounting Position
To change the angle of the lever, loosen the hexagon-head bolts
on the side of the lever.
The operation indicator plate has protruding parts which engage
with the lever, thus allowing changes to the lever position by 90
°
.
The back of the operation indicator plate has no protruding parts.
The lever can be set at any angle by attaching the operation
indicator plate to the Switch so that this side will face the lever. In
this case, however, the D4B-
N will not be approved by SUVA or
BIA. Make sure that the lever engages with the operation
indicator plate securely so that the lever will not slip.
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.
WIRING
Do not connect the bare lead wires directly to the terminals, but
you must connect each of them by using an insulation tube and
M3.5 round solderless terminals and tighten each terminal screw
within the specified torque range.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm
2
) in size.
