SECTION 2. TOWER INSTALLATION
2-4
2.1.5 UT30 10 M TOWER ASSEMBLY
1. Having previously installed the base and
bottom tower section (Section 2.1.4), remove
the bolt from the rear tower leg, and loosen
the bolt in the side legs so the bottom tower
section is free to hinge. Tilt the tower section
to the ground and assemble the remaining
sections and mast using the hardware
provided with the tower.
2. Install the guy wires to the top of the tower
(Figure 2.1-8). Cut the 120' piece of guy wire
into three pieces; lengths will vary with slope.
Attach the guy wires to the tower using two U-
bolts for each guy wire.
3. Mounting brackets and sensors that attach to
upper tower sections are most easily attached
while the tower is lying on the ground.
4. "Walk" the tower to its upright position and
install the remaining bolts in the tower base.
5. Attach the guy wires to the anchors (Figure
2.1-9). Unscrew the jaw and eye bolts until 1
inch of thread extends through the turnbuckle
body. Attach the jaw end of the turnbuckles to
the anchors. While holding the tower plumb,
attach the guy wires to the eye end of the
turnbuckles using a thimble and two U-bolts
for each guy wire. Tighten the turnbuckles
until the guy wires are snug and the tower is
plumb. Do not overtighten the turnbuckles.
2.1.6 UTGND TOWER GROUNDING KIT
1. Drive the ground rod close to the tower
(Figure 2.2-1) using a fence post driver or
sledgehammer. Drive the rod at an angle if
an impenetrable hardpan layer exists. In hard
clay soils, a gallon milk jug of water can be
used to "prime" the soil and hole to make
driving the rod easier.
2. Loosen the bolt that attaches the clamp to
the ground rod. Insert one end of the 4
AWG wire between the rod and the clamp
and tighten the bolt (Figure 2.1-10).
3. Attach the tower grounding clamp to a
tower leg (Figure 2.1-11). Route the 4
AWG wire attached to the ground rod up
the tower leg to the grounding clamp.
Loosen the set screw and insert the 4 AWG
wire and the 24 AWG enclosure ground
wire into the hole behind the set screw and
tighten the set screw. Route the green wire
to where the enclosure will be installed.
