Lift Ring Installation
A lift ring is provided with the microBTS. Secure the lift ring to the side of the enclosure as
shown in
using the two 5/8-inch long 1/4-20 socket head screws and two 1/4-inch split
washers provided. Use a torque wrench with a 3/16-inch hex key socket to tighten the cap screws
to 40 – 45 lbs/force-inches (4.5 to 5.1 Nm) of torque. Do not overtighten. If the threads show
signs of damage, yielding, or stripping when tightening the cap screws, discontinue lift ring
installation and remove the lift ring. Always use appropriate lifting equipment when hoisting the
enclosure into position for mounting. Remove the lift ring after the enclosure has been mounted.

Standard Mounting Bracket Installation
A standard mounting bracket is provided with each enclosure. The standard mounting bracket
may be mounted
vertically or horizontally
. If mounted horizontally, it is recommended that the
bracket be oriented so the enclosure cooling fins will face upward or to the side with respect to
the ground. The following sections provide instructions for installing the standard mounting
bracket on a wood-framed wall, masonry wall, wooden utility pole, or metal pole. Refer to the
procedure that applies to the installation.
5.3.1
Wood-Framed Wall Mounting
When mounting the enclosure on a wood-framed wall, it is recommended that pressure-treated
plywood with a minimum thickness of 0.75-inch (19.0 cm) be used as a backer board. The
backer must be firmly secured to the interior framing of the wall. Use the following procedure to
install the standard mounting bracket on a wood-framed wall:
1. Mount the plywood backer (not-provided) on the wall and firmly secure it to the wall’s
interior studs.
2. Hold the enclosure mounting bracket in position for installation on the plywood backer as
shown in
. The end with the V-notch should be at the top.
