E5@C-T Digital Temperature Controllers User’s Manual (H185)
• 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.
The stripping length is 6 to 8 mm.
• 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.
• Use the following types of crimp terminals for M3.0 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.

Power Consumption
• These models have reinforced insulation between the input power supply, the relay outputs, and
other terminals.
z Inputs
Refer to 2-2-1 E5CC-T Terminal Block Wiring Example or 2-2-2 E5EC-T/E5AC-T 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.
