*The control board can be powered externally by
connecting an external power source to terminal 30.
This voltage is sufcient for parameter setting and for
keeping the control unit active. Note however that the
measurements of the main circuit (e.g. DC-link voltage,
unit temperature) are not available when the mains is not
connected.
