The power supply is connected directly to the mains AC line.
Caution:
•
Do not connect VN- to PE. In a direct-to-mains connection the VN- must
not be connected to the PE. Connecting the VN- to the PE will cause
irreparable damage to the system.
•
Be careful 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.

Multiple Connections Topology
In a multi-axis application it is likely that a single power supply can feed several drives in
parallel.
This topology is efficient and cost saving, by reducing the number of power supplies and the
amount of wiring. Most importantly it utilizes an energy sharing environment among all the
drives that share the same DC bus network.
