Stop!
The DC-bus voltage thresholds of the 93XX controller and the 934X supply unit
must be set to the same value.
Note!
Z2 is selected after balancing the power in the DC-bus. If the power supply of the
supply is not sufficient, a parallel supply can be installed via the mains input of a
controller (see Network of severval drives with decentral supply).
