A V net coupler cable is used to link the V net coupler unit and processor module. The modu-

trated in the following figure. However, following drawing shows a dual-redundant system. If
the processor is single, CN3 will not be used.
• Use the bus1 cable to connect CN2 of coupler unit to BUS1 connector on left side pro-
cessor module.
• Use the bus1 cable to connect CN3 of coupler unit to BUS1 connector on right side pro-
cessor module.
• Use the bus2 cable to connect CN2 of coupler unit to BUS2 connector on left side pro-
cessor module.
