Installing the iRM4451nn00-2
6-6 iRM4451nn00-2 iRRH Product Description and Installation Guide
NOTE
The Installer must provide two (2) M12 anchors, designed for outdoor use, that
are compatible with the type structure on which the iRM4451nn00-2 is to be
installed.
To install mounting plate on a wall:
1. Determine the location where the mounting bracket is to be installed.
NOTE
The center-to-center distance for drilling holes to install the selected anchor is
5.5 in (140 mm).
2. Using a tape measure and spirit level, mark where the anchor will be installed
using a center punch.
3. Drill the holes where the anchor or fastener will be installed on the wall using a
drill bit sized for the anchor or fastener, and insert anchor or fastener.
4. Install the iRM4451nn00-2 mounting bracket to the wall using the two (2) selected
fasteners and supplied by the Installer.
5. Tighten the fastener to torque specified by the fastener/anchor manufacturer
using a torque wrench.
6.4 Hoisting the iRM4451nn00-2 on elevated structures
Hoist line eye bolt screw inserts are located on both sides and on top of the unit. The
recommended hoist line lift points for the iRM4451nn00-2 using the side screw inserts
is shown in Figure 6-5. Installing the hoist line lift eyebolts in the screw inserts on the
top of the unit (not shown) are also recommended. These are the ONLY recommended
points of attachment when hoisting the iRM4451nn00-2 into position on elevated
structures.
An Installer-supplied 2-leg nylon lift sling is attached to the eye bolts and the
iRM4451nn00-2 is lifted directly from the packing container to the mounting location.
WARNING
Because of the variation that may exist among mounting environments, the
Installer is solely responsible for determining an industry-approved, safe
method of hoisting the iRM4451nn00-2 into position onto elevated structures.
NOTE
A tag line, to control sway during the lift, can be attached to either eye bolt, or a
third eyebolt can be installed in one of the unused screw inserts located on the
sides of the unit.
