7.2 Tower mounting
The tower mount option is used to attach our enclosures to UT930, UT920, and
ATW towers. An enclosure ordered with the tower mount option will be shipped
with a three-piece bracket for fitting to the top of the enclosure and an identical
three-piece bracket for fitting to the bottom of the enclosure. This mounting
bracket option uses the same three-piece brackets as the mast mount option, except
the pieces are rearranged so that the flanges are on the side of the bracket instead
of in the middle. For the UT930 the distance between the centres of each flange
needs to be 43 cm (see Figures 7-4, 7-5, and 7-6), if mounted on the lowest section
of the tower. For other towers adjust accordingly.
Attach the enclosure to a UT930 tower as follows:
1.
Remove the bolts and nuts connecting the bracket to the enclosure.
2.
Slide out the flange sections so that the distance between the centres of each
flange is 43 cm (see Figure 7-4).
3.
Reattach the bracket to the enclosure using the original bolts and nuts.
4.
Position the enclosure on the north side of the mast.
5.
Place the enclosure at the desired height. Please note that the recommended
lead lengths for our sensors assume the bottom of the enclosure is 90 cm from
the ground.
6.
Use the furnished 46 mm centre u-bolts to secure the enclosure to the tower
legs.
7.
Route the 14 AWG wire from the brass tower grounding clamp to the
enclosure grounding lug. Strip one inch of insulation from each end of the
wire and insert the end of the wire into the grounding lugs and tighten.
