Connect Pv Panel Sensor (Vsn800-12 Only) - ABB VSN800 Product Manual

Weather Station Electronics Board, Connect Secondary Sensors (VSN800-14 Model)
The Pyranometer sensors are not interchangeable. The Pyranometer sensor supplied with the
weather stations must be wired to Pyranometer #2.
The PV temperature sensor is not polarity sensitive. Therefore, each signal wire is
interchangeable. The sensor comes with a 25ft length of cable. If the temperature sensor is not
used, it should be terminated with a 0-ohm shunt between the positive and negative signal.

Attach the PV panel temperature sensor so it registers the temperature on the
backside of a PV panel. See
mounting considerations.
Connect the sensor to the proper location on the circuit board. Note that the PV Temp
#2 connectors are not used for the VSN800-12 Model.
