A22EA22NE-PCommon Note Common Accessories and Tools 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.

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 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. 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.

• 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. Wiring 1. Connecting Wires to the Push-In Plus Terminal Block Part Names of the Terminal Block Connecting Wires with Ferrules and Solid Wires
• Insert the solid wire or ferrule straight into the terminal block until the end strikes the terminal block. The angle should be approximately 6°.

• 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.

A22EA22NE-PCommon Note Common Accessories and Tools 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. Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use ScrewdriverHammer Do not allow the Switch to drop and hit the floor. Do not place or drop heavy objects on the Switch.
