Wiring Terminals Section 2-2
2-2-3 Wiring
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 supply • With the E5CN, connect to terminals 9 and 10; with the E5CN-U, connect
to pins 10 and 11; with the E5AN and E5EN, connect pins 1 and 2. The
following table shows the specifications.
• These models have reinforced insulation between the input power supply,
the relay outputs, and other terminals.
Input • Make the connections as shown below, using terminals 3 to 5 for the
E5CN, pins 1 to 3 for the E5CN-U, and pins 18 to 20 for the E5AN/EN,
and matching the input types.
Control Output 1 • Outputs are sent from terminals 1 and 2 with the E5CN, from pins 4 to 6
with the E5CN-U, and from pins 3 and 4 with the E5AN/EN. The following
diagrams show the available outputs and their internal equalizing circuits.
