24VDC Power External Second Pyranometer (VSN800-14 Model Only) Twisted Pair Wires Wind Speed and Wind Direction Sensor (VSN800-14 Model Only) Site selection and mounting Weather station location The ideal site is level and well away from obstructions such as buildings, tress, and steep slopes. -
Page 4: Weather Station Mounting Requirements
Lining up the two holes in each mast prevents rotation. At this point the entire unit should be secured to the support structure. It is crucial that the device be oriented as precisely as possible. For the VSN800-14 version, the wind direction measurement is directly related to this positioning. -
Page 5: Sensor Mounting Requirements
If the weather station is going to be used in the Southern hemisphere it must be mounted with the irradiance sensor facing north. In addition, the hemisphere jumper inside the VSN800-14 must be changed from Northern to Southern. -
Page 6: Cabling Requirements To Management System
Beldon 1120A or equivalent cabling should be used. Cables to external sensors are supplied with the sensor. Wiring instructions for the VSN800 series Supply 24VDC Power Run wire from the 24VDC power source to the weather station. -
Page 7: Southern Hemisphere Adjustment
Leave the case open to install the other wires as described in the next section. Southern hemisphere adjustment For the VSN800-14 model, if you are in the southern hemisphere, the jumper at J11 must be set to Southern. If you are in the northern hemisphere, no adjustment is required. J11 is located in upper left section of the circuit board. - Page 8 VSN800 Weather Station Product Manual The RS485 line must be terminated with a 120-ohm resistor. If the device is the only device in the chain or at the end of the chain, you must set the jumper (J8) to terminate the RS485 line. The factory setting for RS485 line termination is OFF.

Connect Second Pyranometer PV Panel Temperature Sensor 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. -
Page 12: Complete The Installation
PV Panel Temperature Sensor Connect PV Panel Sensor (VSN800-12 Model) The PV panel temperature sensor is not polarity sensitive. Therefore, each signal wire is interchangeable. The sensor comes with a 25ft length of cable. If a temperature sensor is not used, it should be terminated with a 0-ohm shunt between the positive and negative signal. -
