Grounding
A SMART System should be electrically grounded at multiple points (the controller, microphones, and in-between) to minimize the potential for damage from electrical discharges.
The SMART System is designed for use on tall, exposed structures like wind turbines and meteorological towers where lightning and electrical surges are likely. To minimize the possibility of equipment damage and data loss, you should ground the SMART System at multiple points whenever possible.
The SMART System can be grounded at the following points:
- Microphones
-
Typically, the microphone is the component of the SMART System most exposed to electrical discharge. Without proper grounding, electricity that discharges to the microphone may travel throughout the SMART System, damaging the microphone, the SMART Controller, and any networking components in between.
The body of each SMART MIC-1 microphone features a non-anodized strip of aluminum. You should apply conductive grease between the microphone and a conductive mounting clamp, then ground the clamp.
- In-Line Surge Suppressors
- Each SMART MIC-1 ships with an RJ45 Surge Suppressor. This should be installed in between the microphone and either the SMART Controller or Ethernet switch, if one is used. The Surge Suppressor should be installed as close as possible to the controller or switch, with the bulk of the Ethernet run in between the Surge Suppressor and microphone, to maximize protection. The Surge Suppressor should be grounded using the pre-installed grounding wire.
- SMART Controller
- Ground the SMART Controller using the exposed grounding nut, adjacent to the power input socket.
