NOTE:
After drilling through a powder coated enclosure, apply an anticorrosive solution
to reduce risk of corrosion. Allow the anticorrosive solution to adequately dry
before installing the strain relief connector. Be sure to completely remove all metal
filings from the interior and exterior of the enclosure using a vaccum cleaner
and/or brush.
Install one of the provided Sealcon strain relief connectors (size M12 X
1.5) for each sensor. Make sure that the gasket is properly inserted
between the connector and the outside of the enclosure and that the
fastener nut is firmly tightened down.
Connect the sensor to their respective input terminal in the enclosure,
See Appendix A for references. Make sure the polarity of the
conductors are marked and are connected to the proper terminals in
the enclosure.
4.1.5
Installing the Solar Irradiation Sensor
The sensor is a two-wire sensor using the red wire for power and the
black wire for the output signal.
WARNING:
Do Not Connect When Energized
Do not connect the sensor wire if the communications module is energized.
Solar irradiation sensors should be mounted away from shadows,
reflective surfaces, and sources of light. Mounting the sensor on the
southernmost (for the northern hemisphere) part of the weather
station should minimize shading from the other weather station
sensors and hardware. The height the sensor is mounted is not critical
for the accuracy of the measurement. However, make sure it is
accessible to facilitate leveling, cleaning and calibration.
