MLM-WB+ • Installation 9
Mounting the MLM-WB+
The procedures in this section enable you to securely mount the MLM-WB+ to a
masonry or nonmasonry wall. These procedures assume that you have already
unpacked the MLM-WB+ and installed necessary cables into the wall or conduits in
conformance with local and national electrical codes and equipment size requirements.
ATTENTION: Potential Damage to Property: All installation and service
procedures should be performed by a qualified Extron installer or an electrician.
Extron is not responsible for equipment failure or damage occurring as a result of
an improper installation.
NOTE: Review UL and ADA mounting and installation requirements (see
Accessibility Requirements on page 4).
WARNING: Risk of Severe Bodily Injury. The MLM-WB+ weighs approximately
63 pounds (29 kg) without equipment installed. To avoid injury, use at least two
individuals to unpack and mount the MLM-WB+, following, as a minimum, these
safe lifting and moving guidelines:
• Avoid lifting with your back.
• Use both hands to hold the MLM-WB+.
• Avoid unnecessary reaching, bending, or twisting.
Selecting a Mounting Location
When determining a mounting location for the MLM-WB+, consider the following factors:
• Type of wall — This section contains installation instructions for both masonry and
nonmasonry walls. In addition, the thickness of the wall and the accessibility of wall
studs determine the number of mounting holes to be used and whether toggle bolts
are required.
• Adequate clearance on all sides of the MLM-WB+ — Keep in mind that when
fully lowered, the door extends out about 20.5 inches (52 cm) from the front of the
MLM-WB+. Sufficient space is also required on each side of the
MLM-WB+ to remove the side panels, to route cables, and to access the rear panel
of any AV device mounted in the 2U rack enclosure.
• Proximity of the MLM-WB+ to installed cables — For example, if you plan to
route cables from the wall into the opening in the back of the MLM-WB+, you should
prepare the cables and position the MLM-WB+ accordingly.
Mounting the MLM-WB+ on a Masonry Wall
To mount the MLM-WB+ onto a brick, stone, or concrete wall:
1. With the help of at least one other person, hold the MLM-WB+ against the wall and
use a carpentry level or similar tool as a guide for leveling the unit.
2. Mark at least six locations for masonry screws to ensure the strength and stability of
the installation. As shown in
figure 8 on the next page, mark four positions to line
up with slotted mounting holes on the MLM-WB+ enclosure and two positions to
line up with round mounting holes (indicated by + marks).
3. Set the MLM-WB+ aside.
