SMA CLUSTER CONTROLLER Installation - Manual (Page 47)

• On the five-pole plug, unlock conductor entries 3 and 4 using a screwdriver and insert the
insulated conductors of the connection cable into the conductor entries. Observe the pin
assignment.
• At terminal X7 in pin rowB, place a bridge between pin 2 and pin 3 and between pin 4
and pin 5.
3. For connection to the Cluster Controller using four-conductor connection technology, perform
the following steps:
• On the five-pole plug, unlock conductor entry 1 using a screwdriver and insert the
insulated conductor of the wire into the conductor entry.
• On the five-pole plug, unlock conductor entries 2, 3, 4 and 5 using a screwdriver and
insert the insulated conductors of the connection cable into the conductor entries.
Observe the pin assignment.
4. Insert the five-pole plug into pin row B in terminal X7.
5. 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.
6. Write down the terminal assignment on the supplied supplementary sheet.
6.11.2 Connecting an Irradiation Sensor
You can connect one irradiation sensor or pyranometer to the Cluster Controller. The measured
value from the irradiation sensor or pyranometer is shown on the display and the user interface of
the Cluster Controller and transmitted to Sunny Portal. In Sunny Portal, the measured values are
used to calculate the performance ratio.
Additionally required material (not included in the scope of delivery):
☐ 1 irradiation sensor
☐ 1 connection cable (see Section 6.3 "Cable Requirements", page 30)
Requirements:
☐ The sensor must be technically suitable for connection to the analog inputs (see Section 9,
page 84).
☐ The connection cable must be prepared for connection to the multipole plug (see Section 6.5,
page 33).
