Gold Drum Power Supply Connections
Figure 11: Non-Isolated from the Mains DC Power Supply connection
Figure 12: Isolated from the Mains DC Power Supply connection
Important Notice
•
In the Isolated connection the G-DRU VN- terminal MUST be connected to the "Earth
Connection" (marked in red in Figure 12 above).
•
In the Non Isolated Connection ( direct to Mains) the VN- terminal MUST NOT be connected to
"Earth Connection"(PE) (Figure 11).
9.6.1.2.
Multiple Connections Topology
In a multi-axis application it is likely that a single power supply can feed several drives in parallel.
The power supply is connected directly to the mains AC line and it feeds more than one drive.
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.
