Safety Precautions
Be sure to read the precautions for All PushButton Switches in the website at: http://www.ia.omron.com/.
Indication and Meaning for Safe Use
Do not perform wiring with power supplied to the Switch/
Indicator. Do not touch the terminals or other charged
parts while power is being supplied. Doing so may result
in electric shock.
• Make sure the Operation Unit and the Switch Unit are properly
assembled.
<Assembling the Operation Unit and Switch Unit>
(1) Assembling the Operation Unit and Switch Unit
Align the TOP indication (the mark ) on the Operation Unit
with the TOP indication on the Switch Unit, and insert the
Operation Unit while keeping the bottom A pressed.
(2) Locking the lock lever
With a screwdriver inserted in the lock hole of the lock lever,
bring the screwdriver in contact with the convex part of the case,
and turn the lock lever until a clicking sound is heard.
• When transition wiring is performed, make sure the switching
current inside the Switch and the current based on the transition
wiring is below the rated current of the Switch.
If a current value higher than the rated current flows, it could result
in emission of heat, or damage and deformation of the Switch,
which could cause fire and locking of the contact, and thus a loss
of safety.
• Do not disassemble or modify the Switch/Indicator under any
circumstances.
• Doing so may prevent the Switch/Indicator from functioning to its
full capability. Do not drop the Switch/Indicator. Do not apply
pressure that may deform or alter the Switch/Indicator.
• The durability of the Switch varies considerably depending on the
switching conditions. Always test the Switch/Indicator under actual
working conditions before application and use the Switch/Indicator
only for the number of switching operations allowed.
• Do not allow the load voltage and current to exceed the rated
value. This may damage or burn out the Switch/Indicator.
• Do not use the Switch/Indicator in locations where explosive or
flammable gases or liquid may be present or scattered. The
electric ark or the heat caused by switching contacts may cause a
fire or explosion.
• Do not use the Switch/Indicator in locations where toxic gases,
such as H
2S, SO2, NH3, HNO3, and Cl2, may be present, or in
locations subject to high temperature or humidity. Doing so may
damage the Switch/Indicator due to contact failure or corrosion.
• Do not use the Switch/Indicator 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 and damaging the Switch/
Indicator.
• Do not use or keep the Switch/Indicator under the following
conditions:
• Subject to severe temperature changes.
• Subject to high humidity or condensation.
• Subject to severe vibration or shock.
• Where direct rays of the sun strike.
• Where sea breeze may be present.
• Make sure that a rubber washer is present between the Operation
Unit and the panel. In models with IP69K, make sure the rubber
bush of the Operation Unit is properly attached.
Otherwise, the specifications of the protective structure may not be
satisfied.
• Do not apply excessive force to the Switch or wirings. Damage or
deformation of the Switch Unit could result in an improper contact
or a loss of safety.
• Use an appropriate wiring and crimp terminals (hereinafter, called
ferrule terminals).
• Exercise caution to avoid wiring errors when connecting the
terminals.
• To prevent wiring materials from smoking or ignition, confirm wire
ratings and use the wiring materials given in the following table.
Use wiring crimp terminals and ferrule terminals of the specified
size.
Warning
