• Separate input leads and power lines in order to prevent external noise.
• Use a shielded, AWG24 to AWG18 (cross-sectional area of 0.205 to 0.823 mm
2
) twisted-pair cable.

for the E5CC-U. The stripping length is 6 to 8 mm for the E5CC, E5EC, E5AC, or E5DC and 5 to 6
mm for the E5CC-U.
• Use crimp terminals when wiring the 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.
• For the E5CC, E5EC, E5AC, or E5DC, use the following types of crimp terminals for M3.0 screws.
For the E5CC-U, use the following types of crimp terminals for M3.5 screws.
In the connection diagrams, the left side of the terminal numbers represents the inside of the Controller
and the right side represents the outside.

*1 The only option number that is possible for the E5CC-U is 000.
• These models have reinforced insulation between the input power supply, the relay outputs, and
other terminals.

Inputs
Refer to 2-2-1 E5CC Terminal Block Wiring Example, 2-2-2 E5CC-U Terminal Block Wiring Example, 2-2-3
E5EC/E5AC Terminal Block Wiring Example, or 2-2-4 E5DC Terminal Block Wiring Example for the terminal
arrangement. When extending the thermocouple lead wires, be sure to use compensating wires that match the
thermocouple type. When extending the lead wires of a resistance thermometer, be sure to use wires that have
low resistance and keep the resistance of the three lead wires the same.
