It may be necessary in some locations tocontact a local contractor to ensure that local electrical codes have been met by the installer.Position the wind sensor onto the end of the mast or mounting arm. Secure the sensor to the mastusing the set screws provided in the sensor base. Do not use excessive force when tightening thescrews. Tighten the screws until the sensor base can no longer be manually rotated.5.3 Cable InstallationThe PVC jacket of the cable will last for many years outdoors under normal circumstances. In harshenvironments it may be necessary to protect the cable with conduit.Route the sensor cable down the mast and to the monitoring equipment in the most direct manner.Leave a "drip loop" of cable below the entry point to the equipment enclosure to help keep moistureout. Fasten the cable to the mast with cable ties to prevent whipping during high velocity winds. Forbest results, use plastic cable ties that are resistant to ultra-violet radiation and place them at two footintervals. Do not over-tighten. Avoid sharp bends, excessive twisting, scrapes and nicks.5.4 Anemometer Wire DiagramSpeed SignalSpeed GroundReed SwitchRedBlackClearEarth Ground3 PER REVWire Diagram for 200-WS-01B Wind Speed SensorNOTE: The shield wire in the sensor cable is electrically connected to the shaft holding the bearing /cup assembly. The purpose is to bleed off static that would otherwise affect the sensor output.Therefore it is important to earth ground the shield wire for best results.5.5 Anemometer MaintenanceWind sensors experience vibration due to high velocity wind. The vibration can loosen the mountingscrews or the support structure. Regular inspection of the mounting hardware is required to preventdamage to the sensor.
