Wiring

Always shut off the power supply (breaker) before installing or uninstalling the Communication Adaptor.

Remove the two screws at the front of the unit and remove the upper case.

Arrangement of the terminal board and switches

(1) Connecting the power supply

The unit can use AC power sources between 100 and 240 V.

Connect the power supply to terminals 2 (N) and 3 (L) on the power terminal strip CN1. (Connect the AC neutral end to N.)

Connect the ground line securely.

(2) Connecting the communication line

●

For the Communication Adaptor control wires, use only two-conductor shielded wire with a cross-section between AWG#20 and AWG#14

(MVVS or CPEVS).

●

Be sure to ground only one end of the shielding.

●

The overall length of each line should be 3280 ft. or less.

●

Do not run the communication line through the same conduit as the power supply, use the same cable as the power supply, or run close to

the power supply line (maintain at least 11-13/16 in. separation).

●

Do not run the LINK1 and LINK2 signal lines through the same conduit, use the same cable for wiring, or run them close together.

●

Use different communication and power cables so they can be differentiated visually.
