Safety Precautions

Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches” .

D4BS

Precautions for Safe Use

• Do not use the Switch submersed 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. (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.)

• 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.

Stopper Installation

Do not use a Switch as a stopper.

Be sure to install a stopper as shown in the following illustration when

mounting the Switch and adjust the stopper so that the Operation Key

is within the setting zone.

Do not subject the Switch to a shock that exceeds the Switch's shock

resistance of 1,000 m/s2.

model.

*2. Apply a torque of 4.90 to 5.88 N·m for an Allen-head bolt. For a

pan head screw, apply a torque of 2.35 to 2.75 N·m.

With a Three-conduit Model, the Switch can be mounted more

securely at four points rather than with just two mounting holes, i.e.,

by adding two studs at the bottom of the switch, each of which is 5 mm

Use spring washers to mount the Switch and Operation key, and

tighten the screws to a suitable torque.

To ensure safety, use screws that cannot be easily removed or

another means to prevent the Switch and Operation Key from easily

being removed.
