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.
Specifications for the logic connection terminals are in the following table:
Note 1: The two terminals [L] are electrically connected together inside the inverter.
Note 2: We recommend using the top row [L] logic GND for logic input circuits and
the [L] GND on the bottom row of terminals for analog I/O circuits.
Note 3: Default relay N.O./N.C. configuration is reversed. See page 4–37 .
