Procedure:
1. Connect the connection cable to the analog signal source (see the manual from manufacturer).
Trim the unneeded insulated conductors up to the cable shield and note down the conductor
colors.
2. Connect the connection cable to the eight-pole plug:
• Unlock conductor entry 8 with a screwdriver and insert the insulated conductor of the
wire into the conductor entry.
• Unlock conductor entries 6 and 7 with a screwdriver and insert the insulated conductors
of the connection cable into the conductor entries. Observe the pin assignment.
3. Insert the eight-pole plug into pin row

.
4. On the connection cable, mark the terminal and the pin row to which the connection cable is
assigned. Use the supplied cable tie with caption field.
5. Write down the terminal assignment on the supplied supplementary sheet.
