6.3 UT6, UT10, UT20, and UT30 tower
installation
The “–TM” option is used to attach an enclosure to a tower. An enclosure ordered with the “–TM”
option will be shipped with a three-piece bracket mounted to the top of the enclosure and an
identical three-piece bracket mounted to the bottom of the enclosure. This mounting bracket
option uses the same three-piece brackets as the “–MM” option, except the pieces are rearranged
so that the flanges are on the side of the bracket instead of in the middle. The distance between
the centers of each flange needs to be 26 cm (10.25 in) for the UT6 and UT10, or 43 cm (17 in) for
the UT20 and UT30 (see
FIGURE 6-9 (p. 16), FIGURE 6-10 (p. 16), and FIGURE 6-11 (p. 17)).
Attach the enclosure to the UT10 tower legs as follows:
NOTE:
Enclosures with the “–TM” option are shipped configured for the UT6 and UT10 towers. Steps
1 through 3 of the following procedure are for configuring the bracket for attachment to a
UT20 or UT30 tower. When mounting to a UT6 or UT10, begin on step 4.
1. Remove the bolts and nuts connecting the bracket to the enclosure.
2. Slide out the flange sections so that the distance between the centers of each flange is
43 cm (17 in) (see FIGURE 6-9 (p. 16)).
3. Reattach the bracket to the enclosure using the original bolts and nuts.
4. Position the enclosure on a side of the tower facing away from the equator.
5. Place the enclosure at the desired height, typically 1 m (3 ft) from the ground.
6. Use the furnished 1.5-inch U-bolts to secure the enclosure to the tower legs.
7. Route the 14 AWG wire from the brass tower ground clamp to the enclosure ground lug.
Strip 2.5 cm (1 in) of insulation from each end of the wire and insert the end of the wire
into the ground lugs and tighten.
