The 12V (pin7) can be used as the supply voltage to the sensor. Optionally, an external power supply
can be connected to the sensors if a different input voltage to the sensor is required.
For an example of sensor connection, refer to Sensor Connection Example on page 29.

CAUTION!
Excessive voltage on the sensor input can damage the SolarEdge gateway. Refer to input ranges
specified in Appendix A: Technical Specifications on page 46.
► To connect a current sensor:
Use a 3-wire cable for this connection. Recommended wire size is 0.52 mm

length of 50m/164 ft.
1 Connect a current source sensor to either I+ or I-, depending on its operating range:

For positive current:
 I+ (pin 5) - connect to the current output (Iout) of the sensor
 I- (pin 4) - connect to ground.
 GND (pin 6) - connect to the ground connection terminal of the sensor
 The 12V (pin7) can be used as the supply voltage to the sensor. Optionally, an external power
supply can be connected to the sensors if a different input voltage to the sensor is required.
