Figure2.27 Wiring for serial communication cards
The serial communication card is labeled “COM”.
The external I/O cutoff output (power cutoff signal) (L) is also wired.
The shield is grounded at the earth bar in Figure 2.22. Remove the cover on the upper right of the
electronics section and perform wiring.
