Page 9: Product Overview
Junction box containing the component board Flange for mounting Vaisala Wind Vane WAC155 converts the digital data that is supplied by Vaisala WA15 series wind sensors into standard serial line messages. The transmitter consists of a component board in a junction box and a cross arm for mounting the wind sensors. -
Page 10: Esd Protection
Any modification voids your warranty. 2.2.1 ESD Protection Electrostatic Discharge (ESD) can damage electronic circuits. Vaisala products are adequately protected against ESD for their intended use. However, it is possible to damage the product by delivering electrostatic discharges when touching, removing, or inserting any objects in the equipment housing. -
Page 11: Installation
Additional protection is needed in regions with frequent, severe thunderstorms, especially when long line cables (>30 m (98 ft)) are used. Vaisala recommends using a surge protector, such as WSP150, in all sites with an elevated risk of a lightning strike. -

6. Reattach the cover with the four screws. 7. Attach the unit on the top of a pole mast with the mounting clamp. Mounting WAC155 on Top of Pole Mast (page 27). 8. Mount the sensors to the cross arm. -
Page 16: Connections
In marine applications, you must remove the grounding screw. 3.4 Connections WAC155 provides the line cable entry through a gland for a cable with a diameter from 7 to 10 mm. For better protection against RF interference, bend the cable shield. -
Page 17: Figure 6 I/O Connectors
Chapter 3 – Installation WAC155 has 3 plug-in I/O connectors: X1, X2, and X3. The terminals accept wires with maximum cross-section area of 1.5 mm Figure 6 I/O Connectors For the location of the connectors and the cable routing through the cable glands, see Sensor Wiring. -
Page 18: Cable Connections
The transmitter connects the wind sensors with the cross arm standard cables through 2 cable glands. Through the cables, the WAC155 transmitter both feeds the sensor power and receives wind data. Plug‑in type screw terminal connectors are provided both for the sensor cables and the output line cable. -
Page 19: Signal Output
- z, A - Z (case-sensitive), and numbers 0 - 9 are accepted. Typically, only a 4-wire shielded cable is required for the line between WAC155 and the host. Two of the four wires provide the operating power for the system. The other two wires are for the RS-485 serial line. -
Page 20: Powering
Service Connector and Jumper Settings (page 13). 3.5.1 Optional Heating Power WAC155 also provides the sensors with a throughput and control of heating power, which can be connected if sensor heating is required. The heating power circuit is galvanically isolated from the operating power circuit. -
Page 21: Figure 9 Heating Power Connection With 40 V Power Supply
The heating power connection requires an extra pair of wires. Since the required heating current for the WA15 series is typically 0.5 ... 1 A, it is most conveniently supplied from a local power source. WAC155 automatically connects heating power in temperatures below +4 °C (39.2 F). -
Page 22: Figure 10 Heating Power Connection With 20 V Power Supply
WAC155 User Guide M210822EN-E Figure 10 Heating Power Connection with 20 V Power Supply When you only install one sensor, anemometer WAA151 or wind vane WAV151, you must use a 20 V power supply and replace the missing sensor heating element with a jumper wire. In this case, only 0.5 A is typically consumed. -
