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. The specified torque is 0.5 N·m for the
E5CC-U.

Crimp Terminals
For the E5CC, E5EC, E5AC, E5DC, or E5GC, use the following types of crimp terminals for M3 screws.
For the E5CC-U, use the following types of crimp terminals for M3.5 screws.
• If you use crimp terminals for the E5DC, use crimp terminals with insulation sleeves. If you use a bare
crimp terminal with no insulation, the terminal may short with the terminal above or below it. If you
use bare crimp terminals, cover the crimped sections with insulating marking tubes. Secure the
marking tubes so that they do not move.
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.
