2-cable system
or
4.6 Connecting the Sensor to the Sunny Central
At the Sunny Central, the sensor is connected to the Sunny Central Control using the terminal strips
Z5-X5.
4.6.1 Irradiation Sensor
In this case, an analog input is used as the voltage input. To do so, the positive pole of the reference
cell is connected to terminal 5 or 7 and the negative pole of the reference cell is connected to terminal
6 or 8.

Protect connection interfaces against weather effects.
When extending the sensor cable, protect the connection interface against weather effects
(e.g. using a junction box or terminal box).
Realizing the electrical connection
The wiring diagram provided must be used for establishing the electrical connections and
connectors.
