Installation and Connection
3.4.6 UC11 Connections
The DIM1 and DIM2 digital inputs located on the IPS1 board (Figure 3.32 and 3.34) monitor F408 and
F410 faults. They are CLOSED when running in normal operation and they are OPEN when the converter
is under any fault condition.
- The DIM1 digital input is connected at XC1:4 and XC1:5 (common).
- The DIM2 digital input is connected at XC2:4 and XC2:5 (common).
