Safety Precautions
Indication and Meaning for Safe Use
Indicates a potentially hazardous situation
which, if not avoided, will result in minor
or moderate injury, or may result in
serious injury or death. Additionally there
may be significant property damage.

WARNING
Precautions
for Safe Use
Supplementary comments on what to do
or avoid doing, to use the product safely.
Wiring
•
Use an appropriate wire size (0.5 to 0.75 mm
2
) for the applied
voltage and carry current.
•
Do not use a #110 tab receptacle.
•
Wire according to the terminal numbers. Mistaken wiring may
damage the Switch and result in fire.
•
Wire according to the terminal arrangement.
•
Use good-quality 6:4 (tin:lead) solder.
•
Use a resin flux cored solder.
•
Do not use a liquid or chlorine type flux.
•
Perform soldering within 3 s using a 30-W max. soldering iron
(temperature at the tip of the soldering iron: 350°C max.). Insulate
with an insulation tube.
•
Do not move the terminal for at least one minute after soldering.
•
Do not apply a force that would deform the terminal when wiring.
!WARNING
Do not wire the Switch or touch any terminal of the
Switch while power is being supplied. Doing so may
result in electric shock.
Always use the Switch in a system that is operated
directly by hand. Do not operate the Switch with a
mechanical actuator. Insufficient Switch strength may
result in damage to the Switch, electric shock, or fire.
Design a safe system for using the Switch, based on a
risk assessment that takes into account all reasonably
foreseeable malfunctions.
Determine the Switch mounting direction and structural
design only after thorough risk assessment. For
example, in a structure where the Switch protrudes from
the pendant perimeter, the weight of the pendant itself
could place the Switch into the enable condition and
operate the machine. Likewise, in a buried structure
where the Switch lies below the surface of the pendant,
the Switch may not enter the grip condition when
pressed and thus fail to stop the machine.
Configure the system so that the machine operates only
when the Switch is in the enable position.
Operating Environment
Prior to using the Switch in places that are subject to contact with oil,
water, or chemicals, check the effect of those substances on the
Switch.
Some types of oil, water, and chemicals will degrade the sealing
capability, which may result in contact failure, defective insulation,
ground fault, or burning damage.
Improper Operating Environment
•
Do not use the Switch in places that are subject to sudden
temperature change.
•
Do not use the Switch in places that are subject to high
temperatures and condensation.
•
Do not use the Switch in places that are subject to strong vibration.
•
Do not use the Switch in places that are subject to direct contact
with machine filings or dust.
Precautions for Correct Use
Mounting
Use M3 screws and flat washers or spring washers to mount the
Switch securely. Use a tightening torque of 0.39 to 0.59 N·m.
Storage
•
Do not store the Switch in places with hydrogen sulfide or other
corrosive gas or sea breeze.
•
Do not store the Switch in places where the level of dust is high
enough to be visible.
•
Do not store the Switch in direct sunlight.
•
Do not impose excessive force on the Switch during storage.
Otherwise, the Switch may deform.

Handling
•
Do not drop the Switch. Otherwise, the Switch may malfunction.
•
Do not apply strong vibration or shock to the Switch. Otherwise, the
Switch may malfunction or be damaged.
Do not contact the Switch with sharp objects. Otherwise, the
Switch may be scratched. Scratches on the operating portion of the
Switch may result in problems both in appearance and operation.
