Assembling FS11P
To assemble the FS11P system, proceed as follows:
1. Mount the base plate and level it with six M16 nuts (see Figure 9
below). If Background Luminance Sensor LM21 is installed, align
the base plate with the desired background luminance viewing
direction as shown in Figure 9 below and Figure 11 on page 39.
NOTE
If the frangible mast length is more than 3 meters, do not install the
tilting support
supplied in the Foundation kit FS211296.
2. If you are installing a frangible mast, mount the pole mast pedestal
on the base plate with three M16 nuts (see Figure 11 on page 39)
and an M8 hinge bolt. For the M16 nuts use the wrench supplied
with the FSA11 kit.
