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 or E5ED (models with screw terminal blocks)
Wires
Use the wire specifications given in the following table.
Model
E5CD or E5ED
• 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.

 E5 D-B (Models with Push-In Plus Terminal Blocks)
1. Connecting to the Push-In Plus Terminal Block
• Part Names of the Terminal Block
• Connecting Wires with Ferrules or Solid Wires
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.
