4.7.2.1.a Three-Phase Direct-to-Mains Connection Topology
Figure 9: Non-Isolated Three-Phase Connection Topology
Caution:
• Do not connect VN- to PE. In a direct-to-mains connection the VN- must
not be connected to the PE, as this will cause irreparable damage to the
system.
• Take care and note that in a direct-to-mains connection the Neutral point is
not the most negative voltage level. It is the mid-point level of the rectified
DC bus.
