A22NE-PD A22NE-P A22E Common Note
Common Accessories and Tools
• 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 product is intended for indoor use only. Using the product
outdoors will 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.
• When mounting on a device with high airtightness, test operation
in advance. There is a risk that the negative pressure will prevent
the Operation Unit of from returning.
• Although the contacts of an A22NE-PD can be used with both the
standard loads and microloads, once a contact has opened or
closed under a load, you cannot again connect a small-capacity
load. Doing so could roughen the contact surface, and result in
loss of contact reliability.
• In the case of loads where an inrush current occurs when the
contact is opened or closed, the durability may reduce due to
extreme wear on the contacts.
If necessary, insert a contact protection circuit.
• If a contact weld, the lock lever might not return to the release
position, and contact inversion might not occur. In such a case,
move the lock lever to the release position, and remove the Switch
Unit from the Operation Unit.
Wiring

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.
• If a wire is difficult to connect because it is too thin, use a flat-blade
screwdriver in the same way as when connecting stranded wires.
Connecting Stranded Wires
Use the following procedure to connect the wires to the terminal block.
1. Hold a flat-blade screwdriver at an angle and insert it into the
release hole. The angle should be appropriately 10 to 15°. If the
flat-blade screwdriver is inserted correctly, you will feel the spring
in the release hole.
2. With the flat-blade screwdriver still inserted into the release hole,
insert the wire into the terminal hole until the end strikes the
terminal block.
3. Remove the flat-blade screwdriver from the release hole.
