Specifications of Control and Logic Connections
The control logic connectors are located just behind the front panel half-door. The relay
contacts are accessible behind the main door. 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.
