Precautions When Wiring - Omron E5*C Series User Manual

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.
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.
Select a crimp terminal that can be tightened as shown below. (Excluding the E5CC-U)
E5CC, E5EC, or E5AC
Note:
Be careful in the tightening direction, as
the terminal block is at an angle.
Some terminal blocks have a large crimp part. In this case, bend the terminal in advance as shown in the figure,
and tighten slowly to ensure that the terminal screw is vertical to the terminal surface of the terminal block.
For the E5CC-U, use the following types of crimp terminals for M3.5 screws.
