Sensor Wiring

The transmitter connects to the wind sensors with the cross-arm's

standard cables through two cable glands. Through these cables the

WAC155 transmitter both feeds the sensor power and receives the wind

data. Plug-in type screw terminal connectors are provided both for the

sensor cables and the output line cable.
