Wire colors may vary between different sensors. It is up to the
installer to take into account any mismatched wire colors
between the sensor and pigtail wire when connecting wires to the
A150. NOTE

FIGURE 5. A150 with PWENC Connector
When using the A150 to wire a sensor to a PWENC connector,
ensure the wiring inside the pre-wired enclosure corresponds
with the wiring from the sensor. NOTE
Figure 6 gives an example of an anemometer wired to an A150. Note that the
green wire in the PWENC connector must be connected to a datalogger’s pulse
input inside the enclosure for the signal to be measured.
