The NFE power unit, NXP Control and the external control accessories need external 24Vdc supply.
A minimum of 2A power is required to ensure proper operation. See the connection from circuit
diagrams Figure 98 - Figure 101. The cable between the NXP control and the power unit has to be
shielded and grounded using the cable clamp which is included in the delivery of the drive.
The main circuit breaker control requires typically external 230Vac, and a minimum of 2A.
