To protect personnel and the wind sensor, install an air terminal with the tip at least one meter above WMT700. The air terminal must be properly grounded,
compliant with all local applicable safety regulations. Do not install the wind sensor above the top of the air terminal.
WARNING!
Do not perform installation or maintenance procedures when there is a risk of thunderstorm or lightning activity in the area.
WARNING!
Handle with care. Any impact on the instrument or sensor array may cause damage and lead to incorrect measurements.
CAUTION!
Save the container and all the packaging materials for future transporting or shipping Mounting with WS425 Mounting Kit
You can mount WMT700 either on a vertical pole mast or a horizontal cross arm using the
WS425 mounting kit. The procedure for both mounting options is identical. Typically you can upgrade from WS425 to WMT700 without removing the mounting kit.
If you remove the mounting kit, you must align the wind sensor after mounting. To facilitate the aligning process, mark both the wind sensor and the mounting kit with a marker pen before removing the mounting kit. You can use the mark as a rough reference when starting the aligning process described in
4.7 Aligning WMT700 (page When mounting WMT700 to across arm, the wind sensor can be placed with the array facing up or down. If the wind sensor is installed with the array facing down, you must configure WMT700 accordingly. See
5.3 Configuration (page Chapter 4 – Installation

Figure 40 FIX, WS425FIX60-RST, and WS425FIX60-POM
• Correct mounting adapter for your installation FIX, WS425FIX60-POM, or
WS425FIX60-POM. The diameter of the mounting adapter for the adapters is 61 mm.
Change the mounting adapter if necessary. If you are not sure that you have the correct mounting adapter, contact Vaisala.
Figure 41 Mounting Adapter for FIX, WS425FIX60 (Left, and Mounting Adapter for
FIX70 (Right)
• Correct cables for the mounting kit and analog output/serial communication. The table below lists the available cables fora retrofit installation. The In/Out stands for the possibility to route the cable either inside or outside of the mast.
If you have FIX, do not use the adapter cables but order the appropriate WMT700
cable. The adapter cable does not fit inside the mast.
