If you have WA25, you configure WAC155. See Configuring WAC155 for WA25.

No external operating voltage

The following figure shows the simplest wiring for the WA25 series wind sensors with Vaisala Mains Power Supply WHP25. WAA252 supplies WAC155 with the operating power (+12 Vout to X2/3). No external operating voltage is applied to connector X2. The expansion connector required for high-current wiring is included in the WAA252 accessories.

WHP25 is sold only as a spare part.
