Lead free / RoHS Compliant
Precautions
If the D4B-jN is applied to an emergency stop circuit or safety
circuit for prevention of injury, use the D4B-jN model that has an
NC contact equipped with a force-separation mechanism, and
make sure that the D4B-jN operates in the positive mode. In
addition, secure the D4B-jN with screws that are tightened in a
single direction so that the D4B-jN cannot be easily removed.
Then provide a protection cover for the D4B-jN and post a
warning label near the D4B-jN.
In order to protect the D4B-jN from damage due to
short-circuiting, connect a fuse breaking a current 1.5 to 2 times
higher than the rated current in parallel with the D4B-jN.
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-jN to the door without applying a stopper
to the door.
If the D4B-jN is used with the actuator normally pressed, the
D4B-jN may malfunction or may soon have reset failures. Be
sure to check and replace the D4B-jN regularly.
CW, CCW or Two-way Operation
The head of Side Rotary Switches can be converted in seconds to CW, CCW, or two-way operation. The conversion procedure follows.

Procedure
1. Remove the head by loosening the four screws that secure it.
2. Turn over the head to set the desired operation (CW, CCW, or both). The desired operation can be
3. Set the CW hole on the head at the operation position mark (arrow) for clockwise operation or set

the CCW hole right at the arrow for counterclockwise operation. In either case, be sure to set the
hole position exactly at the arrow point.

Tightening Torque
Note: Apply a tightening torque of 0.78 to 0.88 N S m to conduit
Since loose screws may
cause a malfunction,
tighten each screw to the
appropriate torque.
