Figure 3.32 Frame 3A 700S Phase II Control Synchronization Cable Connection
Inverter-to-Converter DPI Communication Cable
To enable the Inverter and Converter section of the Frame 3A Power
Module to communicate with each other, a factory-installed DPI
communication cable is used. No user connection is required.
Synchronization
Connections for Frame 3B
Coupled or Stand-Alone Inverter Power Modules
Frame 3B Inverter Power Modules may be configured in two ways. One
way is an Inverter Power Module coupled with a Converter Power Module.
The coupling is achieved by using two cables: a control synchronization
cable and an inverter-to-converter DPI connection cable. The other way is a
stand-alone Inverter Power Module. In this case, synchronization and DPI
connection cables are not needed to connect the Inverter Power Module to
the Converter Power Module. The two cables for coupling are described in
the next two subsections.
