• 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.
• Tighten the terminal screws to a torque of 0.74 to 0.90 N·m, except for the
E5CZ-U, which is 0.5 N·m.
• Use the following types of crimp terminals for M3.5 screws.
Note Do not remove the terminal block. Doing so may result in malfunction or fail-
ure.
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 E5CZ, connect to terminals 9 and 10; with the E5CZ-U, connect
to pins 10 and 11; with the E5AZ and E5EZ, connect pins 1 and 2. The
following table shows the specifications.

• Reinforced insulation is applied between the input power supply, the relay
outputs, and other terminals.
