2. On the 5-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 ( ).

3. For connection to the module using two-conductor connection technology, perform the
following steps:
• On the 5-pole terminal block, unlock the terminal positions 3 and 4 using a suitable tool
and plug the conductors of the connection cable into these terminal positions. Observe
the pin assignment.
• On the 5-pole terminal block, bridge the
terminal positions 2 and 3 as well as the
terminal positions 4 and 5.
4. For connection to the module using four-conductor connection technology, unlock the terminal
positions 2, 3, 4, and 5 on the 5-pole terminal block using a suitable tool and plug the
conductors of the connection cable into these terminal positions. Observe the pin assignment.
5. To connect the outside temperature sensor, plug the 5-pole terminal block into pin row A on
terminal TEMP-IN.
6. To connect the module temperature sensor, plug the 5-pole terminal block into pin row B on
terminal TEMP-IN.
7. If no further connections are required on the module or in the inverter, close the inverter and
commission it (see the inverter manual).
8. If necessary, configure the temperature sensor (see Section7.2, page26).
6.5 Connecting an Irradiation Sensor
You can connect a maximum of 1 irradiation sensor to the module.
Additionally required material (not included in the scope of delivery):
☐ 1 irradiation sensor
☐ 1 connection cable (see Section6.1, page15)
Requirements:
☐ The irradiation sensor must be technically suitable for connection to the analog input (see
Section9, page31).
☐ The connection cable must be prepared for connection to the multipole terminal block (see
Section6.2, page15).
