Depending on the surface where the RaZON
+
is mounted, the material to secure the tripod or pole mount to the floor or pole is required.
3.3 Site preparations
Before installation of a RaZON
+
the site must be prepared. The following points need to be checked.
The site where the RaZON
+
is placed must be free of obstructions, in order to have the best possible 360 degrees field of view .
Building of a concrete or steel horizontal platform is required for mounting the RaZON
+
tripod or pole mount on. Ensure that the
surface on which the RaZON
+
will be mounted is reasonably level, but above all it is very important to create a very firm base to stand
upon. This is a requirement for (years of) accurate tracking. Both the tripod and pole mount need to be fixed with bolts to the surface
where they are mounted on. Diameters and distances of these mounting holes are given in the next paragraphs.
Make sure that the RaZON
+
is located in such a way that shadows will not be cast onto the radiometers at any time. If a meteorological
mast is placed near the RaZON
+
, make sure the position is such that the location of the mast is between the RaZON
+
and the nearest
pole (North- or South pole). In this way the mast will never block the direct radiation.
A rule of thumb is that the distance of a mast or tree with height ‘h’ should be at least 10 h from the RaZON
+
.
Make sure that the RaZON
+
will be easily accessible for maintenance purposes.
3.4 Mounting and operating area
RaZON
+
, complete with all the accessories attached, requires a substantial amount of unobstructed area to operate properly. This
should be kept in mind when deciding where and how the unit is going to be installed. Figures on the next page show the minimum
operating area with respect to both the Azimuth and Zenith axis of a RaZON
+
complete with all accessories including Tripod Stand and
Shading Ball Assembly.
Keep in mind that the angle of Azimuth (horizontal) rotation changes during the year.
A RaZON
+
installed in the winter will rotate further during summer, so make sure no objects will block its movement. To test / prevent
blocking from its movement it is advised before connecting the power, to rotate the RaZON
+
by hand, fully right and left. This is to
check if the RaZON
+
does not hit any nearby obstacles and if its cables are long enough and can move freely.
