1. Connect signal cable between MBS/PDU, STS shelf.
Connect the 4-pin MBS cable to the CN1 connector on the back PCB of the controller/interface/STS shelf. Then
connect one end of the STS/inverter signal cable to the CN11 connector on the backplane PCB of the controller/
interface/STS chassis. Connect the other end to the CN7 connector on the backplane PCB of the inverter.
2. Connect
bus
bar.
Connect the 5 bus bars accompanied with MBS/PDU to UC3, UC2, UC1 on the STS backplane PCB to the
corresponding connectors of MBS/PDU as shown below:
• Bus bar 3 for (inverter output N)
• Bus bar 3 for (Ground)
• Bus bar 5 x 1 for (inverter output L)
• Bus bar 2 x 1 for (STS output L)
• Bus bar 1 x1 for (AC input L)
