Connect the auxiliary or control supply (single phase 50/60Hz)

fans.

Connect the motor field (-) to terminal D3 and field (+)
to terminal D4. If the motor has no field connections, is
a permanent magnet motor, or if the field is derived externally,
you must override the field failure circuit using the MMI. If the
controller is correctly specified (Product Code), then the
external field option will be provided and the field failure
alarm will be overridden automatically at power-up.
