Appendix C Size Multi-axis Shared-bus Configurations
In this example, two drive clusters in the same cabinet are connected by the
same 276…747V DC-bus voltage. Kinetix 5700 capacitor modules provide
connection points for the DC bus. The extension module is needed only when
the DC-bus system current exceeds 104 A, and can support up to 208 A
maximum external DC-bus current.

IMPORTANT
When two or three DC-bus power supplies are wired together in the same
drive cluster, they must all be catalog number 2198-P208.
