Mounting on Horizontal Cross Arm

When mounting WMT700 on a cross arm, the wind sensor can be
placed with the array facing up or down. Mounting WMT700
with the array facing down provides additional protection against
the accumulation of snow and interference from birds. The
adapter drains located at the bottom of WMT700 prevent water
from accumulating inside the mounting adapter. If the wind
sensor is installed with the array facing down, you must configure
WMT700 accordingly. For configuration instructions, see section
Configuration Parameters on page 118.

Figure 28 on page 69 and Figure 29 on page 70 show the
mounting procedure.

To mount WMT700 on a cross arm:

1.

Attach the FIX70 mounting kit to the cross arm with U bolts
(provided). Insert the U bolts to the vertical slots of the
FIX70 mounting kit. See number 3 in Figure 28 on page 69.

2.

Check that the mounting kit is not tilted to either side.
Tighten the U bolts firmly.

3.

Run the cable through the FIX70 mounting kit.

4.

Insert the cable in the cable tightening tool as shown in
Figure 24 on page 64 to connect the cable to the wind
sensor. Connect the cable to WMT700 and tighten by
rotating the tightening tool clockwise by hand as shown in
Figure 31 on page 72. Ensure that the connector is properly
tightened before proceeding to the next step.

5.

Hold the wind sensor from the enclosure and slide the
sensor into the mounting kit. Turn the sensor so that the
mounting screw slides into the slot. Do not touch the array
when handling WMT700.

To avoid misalignment, turn the sensor until the screw
reaches the far end of the slot. When the screw is in the
position indicated with number 4 in Figure 28 on page 69,
tighten the screw.

6.

Remove the transportation damper protecting the array and
store it for future use.

7.

Align the horizontal cross arm. For instructions, see section
Alignment on page 74.

8.

Connect the cable to the data acquisition system and power
supply. Connect the wires according to section Wiring on
page 77.

WMT700 is now ready for operation.
