Procedure:
1. Connect the connection cable to the irradiation sensor (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 4 with a screwdriver and insert the insulated conductor of the
wire into the conductor entry.
• Unlock conductor entries 2 and 3 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 A in terminal X8.
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.
6. Adjust the characteristic curve of the irradiation sensor or pyranometer via the
Cluster Controller user interface (see the Cluster Controller user manual). The measured
irradiation values can then be shown on the display and the Cluster Controller user interface.
