Note:
1. Main circuit terminals are indicatied with double circles and
control circuit terminals are indicatied with a single circles
2. The CN5 factory setting is NPN
3. To enable the inverter both inputs, BB and BB1 must be closed. If
only one of the inputs is closed, “BB” will be displayed in the
operator panel and the inverter will not start.
