Figure 4-18 Fitting the Labels on the Front Connector
To label a front connector, follow the steps outlined below:
1. Enter the addresses of the individual channels on the two labels. Note the slot
numbers on the labels to record the assignment of front connector to module.
2. Place a label on the left of the opened front connector. The label has a
T-shaped blank in the middle with which you can fix the label onto the front
connector housing. Bend the blank slightly to one side and push it behind the
corresponding cutout of the front connector whilst sliding in the label
(see Figure 4-19).
3. Refit the cover on the front connector.
4. Slide the label with the terminal diagram of the inputs or outputs into the interior
of the cover of the front connector.
5. Slide a label externally into the cover of the front connector.
