Control Logic Signal Specifications

Control Logic Signal Specifications

The control logic connectors are located just behind the front housing cover. The relay contacts are just to the left of the logic connectors. Connector labeling is shown below.

Note 1: The two terminals [L] are electrically connected together inside the inverter.

Note 2: We recommend using [L] logic GND (to the right) for logic input circuits and [L] analog GND (to the left) for analog I/O circuits.

Note 3: Default relay N.O./N.C. configuration is reversed. See page 4–36.
