E5CD/E5ED

Precautions when Wiring

• Separate input leads and power lines in order to prevent external

noise.

• Use crimp terminals when wiring the screw terminals.

• Use the suitable wiring material and crimp tools for crimp terminals.

• Tighten the terminal screws to a torque of 0.43 to 0.58 N·m.

E5CD/E5ED (Screw Terminal Blocks)

Wires

Use the wire specifications given in the following table.

• Strip the wires on which crimp terminals will be used to the length

recommended by the crimp terminal manufacturer.

• Use shielded twisted-pair cables for signal lines to prevent the

influence of noise.

Crimp Terminals

For the E5CD or E5ED, use the following types of crimp terminals for

M3 screws.

Although you can connect two crimp terminals with insulation sleeves

to one terminal, you cannot do so if the diameter of the insulation

sleeves is too large.

@D-B (Push-In Plus terminal block types)

1. Connecting Wires to 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 wire.

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 between 10° and 15°. If the flat-

blade screwdriver is inserted correctly, you will feel the spring in

the release hole.

2. With the screwdriver still inserted into the release hole, insert the

wire into the terminal hole until it strikes the terminal block.

3. Remove the flat-blade screwdriver from the release hole.

Checking Connections

• After the insertion, pull gently on the wire to make sure that it will

not come off and the wire is securely fastened to the terminal block.

• If you use a ferrule with a conductor length of 10 mm, part of the

conductor may be visible after the ferrule is inserted into the

terminal block, but the product insulation distance will still be

satisfied.

2. Removing Wires from Push-In Plus Terminal Block

Use the following procedure to remove wires from the terminal block.

The same method is used to remove stranded wires, solid wires, and

ferrules.

1. Hold a flat-blade screwdriver at an angle and insert it into the

release hole.

2. With the screwdriver still inserted into the release hole, remove the

wire from the terminal insertion hole.

3. Remove the flat-blade screwdriver from the release hole.
