A22NE-PD

• 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

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.

• 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.
