Marking of Modules

For the marking of modules and front connectors, a set of labels is supplied
with the modules for the labeling, and a set of labels with the addresses is
supplied with the central controller. Figure 8-9 shows the locations of the
labels. The self-adhesive address label is pre-printed. You can mark the strips
to identify the signal line terminals.
