Installation
Mounting to the Panel
Assembling the Cap
(1) Preparing the Panel (2) Mounting the Operation Unit on the Panel
• The panel dimensions are shown below.
• The panel thickness must be 1 to 5 mm.
• Always use a 25-mm-dia. A22Z-R25 Lock Ring for a 25-mm-dia. hole.
IP65 degree of protection will be lost if the 25-mm-dia. Lock Ring is not used
because of the larger size of a 25-mm-dia. hole.
• When painting or coating the panel, make sure that the specified panel
dimensions apply to the panel after painting or coating.
• Insert the Operation Unit from the front surface of the panel, insert the Lock
Ring and the mounting Ring from the terminal side, then tighten the Ring.
Before tightening, check that the rubber washer is present between the
Operation Unit and the panel.
• Align the Lock Ring with the groove in the casing, then insert the Lock Ring so
that its edge is located on the panel side.
• Tighten the mounting nut at a torque of 0.98 to 1.96 N·m.
• When using a Lock Ring, replace with the supplied Lock Ring, insert the
projecting part into the lock slot, and then tighten the mounting Ring.
(3) Mounting the Switch on the Operation Unit
• Insert the Operation Unit into the Switch Unit, aligning the arrow mark inscribed
on the Case with the lever on the Switch Blocks, then move the lever in the
direction indicated by the arrow in the following figure.
(4) Removing the Switch
Emergency Stop Switch
• Insert the protrusion of the Tightening Wrench (A22Z-3905) into the Cap slot and then turn to remove the Cap.

as for an ordinary panel.
Place the tip of a screwdriver on the surface
where the cable port hole is to be created
with the cover attached and strike the
screwdriver to punch a hole.
Attempts to punch a hole on the other side
of the case will damage the Box.
1. Insert the connector into the cable port hole in the Box and secure
with the Mounting Ring inside the box.
2. Pass the tightening cap through the cable, insert the cable into the
connector, and tighten the tightening cap to secure the cable.

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
If the Operation Unit is separated from the Socket Unit, the
equipment will not stop, creating a hazardous condition.
Secure the lever on the Socket Unit by using the
A22Z-3380 Lock Plate so that the Operation Unit cannot be
easily separated from the Socket Unit.
(Refer to “Mounting the Lock Plate” at the below.)
Mounting the Lock Plate
1. Confirm that the lever on the Mounting Latch is on the side where
the Operation Unit is secured and then insert the protrusion on the
Lock Plate into the hole in the lever on the Mounting Latch.
2. Press the hole on the Lock Plate onto the protrusion on the
Mounting Latch until it clicks into place.
Wiring
• Terminal screws must be Phillips or slotted M3.5 screws with a
square washer.
• The tightening torque is 1.08 to 1.27 N·m.
• Single wires, stranded wires, and crimp terminals can be
connected to the Switch.
• Applicable Wiring Materials:
Twisted strands: 2 mm2 max.
Solid wire: 1.6 mm dia. max.
• After wiring the Switch, maintain an appropriate clearance and
creepage distance.
LED Lamps
• The LED current-limiting resistor is built-in, so internal resistance
is not required.
• If commercially available LEDs are used, select the ones that meet
the following conditions:
Base: BA9S/13
Overall length: 26 mm max.
Power consumption: 2.6 W max.
When DC-specific LEDs are used, wire the Switch so that the X1
terminal is positive.
• Mis-lighting of the LED
The LED lights with approx. 0.1 mA or less of micro-current. Take
a countermeasure like adding a resistor to prevent mis-lighting in
parallel to the LED.
The micro-current varies with the machine (leak current or stray
capacity between cables, etc.). Select resistance value and
allowable power consumption that meet the actual current.
• Do not use a lamp that does not satisfy the rating.
Using the Microload
Contact failure may occur if a Switch designed for a standard load is
used to switch a microload. Use Switches within the application
ranges shown in the following graph. Even within the application
range, insert a contact protection circuit, if necessary, to prevent the
reduction of life expectancy due to extreme wear on the
contacts caused by loads where inrush current occurs when the
contact is opened and closed.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability
level of 60% (λ 60) (conforming to JIS C5003).
The equation, λ 60 = 0.5 x 10−6/time indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of 60%.
Be sure to read the "Safety Precautions" on page 37.
Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.

(When Using a Ring)
• The small size of the control panel is realized by conserving space
and changing the direction of the wiring.
• Since there is no looseness in the wiring, there is a reduction in
the maintenance efforts.
• A lock lever mechanism that can be easily operated is adopted.
• A maximum of up to six contact points can be combined together
in the contact-point configuration.
• Oil-resistant to IP65 (non-lighted models) / IP65 (lighted models).

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
• If the Operation Unit is separated from the Switch Units, the
equipment will not stop, resulting in a hazardous situation.
Make sure the Operation Unit, Mounting Latches, and the Switch
Units are properly assembled.
<Assembling the Operation Unit and the Mounting Latches>
Align the TOP indication (the mark) on the Operation Unit with
the TOP indication on the Mounting Latches to fit it properly, and
turn the lock lever on the Mounting Latch in the direction shown in
the figure below until a clicking sound is heard.
<Assembling the Mounting Latches and Switch Blocks>
Make sure the hooking part (convex part) on the Mounting Latches
is perfectly latched into the hooking part (concave part) on the
Switch Block.
• 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 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.
• 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 H2S, 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. 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 Block could cause 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.
• After storing the product for a long time exceeding 1 year, perform,
at a minimum, inspections of the operating characteristics, contact
resistance, insulation resistance, and dielectric strength as well as
evaluate the product under the working conditions.
• This Switch/Indicator is intended for indoor use only.
Using the Switch/Indicator outdoors may result in failure.

Common Accessories and Tools
•Do not wire anything to the release holes.
•Do not tilt or twist a flat-blade screwdriver while it is inserted into a
release hole on the terminal block. The terminal block may be
damaged.
• Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if you insert the screwdriver
straight in.
•Do not allow the flat-blade screwdriver to fall out while it is inserted
into a release hole.
• Do not bend a wire past its natural bending radius or pull on it with
excessive force.
Doing so may cause the wire disconnection.
• Do not insert more than one wire into each terminal insertion hole.
• Do not mount A22N-P or A22NE-P Push-In Plus terminal switch
blocks on A22N screw terminal blocks. Doing so may result in
unsatisfactory performance.

A22E A22NE-P Common Note
Common Accessories and Tools
LED Lamps
• A current-limiting resistor is built in the LED lamp, so the
installation of an external resistance is not required.
• Lighting malfunction of the LED lamp
A micro-current of approximately 0.1 mA or less is sufficient to turn
on the LED lamps. Take a countermeasure like adding a resistor to
prevent mis-lighting in parallel to the LED lamp.
The micro-current varies with the machine (leak current or stray
capacity between cables, etc.). Select resistance value and
allowable power consumption that meet the actual current.
Be sure to read the "Safety Precautions" on page 37.

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
Mounting
• Always make sure that the power is turned OFF before wiring the
Switch. Also, do not touch the terminals or other current-carrying
ports while power is being supplied. Electric shock may occur.
• Do not tighten the mounting ring more than necessary using tools
such as pointed-nose pliers. Doing so will damage the mounting
ring. The tightening torque is 0.98 to 1.96 N·m.
• Recommended panel thickness: 1 to 5 mm.
• When mounting the caps after changing the LED or the caps,
tighten the caps at a tightening torque of 0.49 to 0.78 N·m.
Operating Environment
• The IP65 model is designed with a protective structure so that it will
not sustain damage if it is subjected to water from any direction to
the front of the panel.
• The Switch is intended for indoor use only. Using the Switch
outdoor may cause it to fail.
Others
• If the panel is to be coated, make sure that the panel meets the
specified dimensions after coating.
• Due to the structure of the Switch, severe shock or vibration may
cause malfunctions or damage to the Switch.
Also, most Switches are made from resin and will be damaged if
they come into contact with sharp objects. Particularly scratches
on the Operation Unit may create visual and operational
obtrusions.
Handle the Switches with care, and do not throw or drop them.
