Wiring Terminals
Section 2-2
Input • Make the connections as shown below, using terminals 3 to 5 for the
E5CZ, pins 1 to 3 for the E5CZ-U, and pins 18 to 20 for the E5AZ/EZ, and
matching the input types.
Control Output 1 • Outputs are sent from terminals 1 and 2 with the E5CZ, from pins 4 to 6
with the E5CZ-U, and from pins 3 and 4 with the E5AZ/EZ. The following
diagrams show the available outputs and their internal equalizing circuits.
• The following table shows the specifications for each output type.
