Figure 10: Connection of an irradiation sensor with voltage output
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. Depending on the irradiation sensor and the pin assignment of pin row A, identify the terminal
positions on the first 3-pole terminal block that are required for connecting the connection
cable.
3. On the first 3-pole terminal block, unlock the
required terminal positions using a suitable tool ( )
and plug the conductors into these terminal positions
( ).

4. On the second 3-pole terminal block, unlock the terminal position 1 using a suitable tool and
plug the conductor of the cable piece for shielding into this terminal position.
5. When using the supply voltage provided by the module, perform the following additional
steps for the second 3-pole terminal block:
• Unlock terminal position 2 using a suitable tool and plug the insulated conductor for
supply voltage into this terminal position.
• Unlock terminal position 3 using a suitable tool and plug the insulated conductor for the
reference potential of the supply voltage into this terminal position.
6. Plug the first 3-pole terminal block into pin row A on terminal ANA-IN.
7. Plug the second 3-pole terminal block into pin row B on terminal ANA-IN.
8. If no further connections are required on the module or in the inverter, close the inverter and
commission it (see the inverter manual).
9. Configure the irradiation sensor (see Section7.3, page27).
