• Separate input leads and power lines in order to prevent external noise.
• Use AWG24 (cross-sectional area: 0.205 mm
tional area: 2.081 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 0.74 to 0.90 N·m.
• Use the following types of crimp terminals for M3.5 screws.
7.2 mm max.
7.2 mm max.
Do not remove the terminal block. Doing so will result in malfunction or failure.
In the connection diagrams, the left side of the terminal numbers represents
the inside of the Controller and the right side represents the outside.
• With the E5CN-H, connect to terminals 9 and 10; with the E5AN-H and
E5EN-H, connect pins 1 and 2. The following table shows the specifica-
tions.
Input power supply
100 to 240 VAC, 50/60 Hz 8.5 VA
24 VAC, 50/60 Hz
24 VDC (no polarity)
• These models have reinforced insulation between the input power supply,
the relay outputs, and other terminals.
• Make the connections as shown below, using terminals 3 to 5 for the
E5CN-H and pins 17 to 20 for the E5AN/EN-H, and matching the input
types.
