Appendix A Interconnect Diagrams
In this example, the inverter drives and optional capacitor modules are downstream of three DC-bus (converter) power
supplies. When two or three DC-bus power supplies are used, they must be catalog number 2198-P208. This
configuration provides more power (kW) to the drive system.
