CON4 and CON5 are hosting the UCB controller

(Figure 15). Most of the signals that are associated with the

low−power connectors are routed to the UCB controller via

CON4 and CON5. On the contrary, signals like the

IPM_DIS, and the PWM pulses are directed from CON4 and

CON5 to the NFAM5065L4B inverter for control purposes.

High−power Connectors

The high−power connectors that are associated with the

input and output system voltages are illustrated in

Figures 16 and 17. Figure 16 illustrates the DC−Link input

voltage, where the green connector should be connected to

earth, the red connector should be connected to the high

potential (+), and the black to the ground (−). The inverter

output voltages, on the other hand, are available through the

connector CON3 (see Figure 17). The output voltage U, V

and W sequence is shown in Figure 17.
