• 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.

2. Remove the screws attaching the adjustable clamp brackets to the inside of the enclosure. Set the brackets and cover aside.

3. Stack equipment on the door, making sure not to exceed the maximum equipment height of 5.5 inches (14.0 cm) or the maximum rack depth of 16.0 inches (40.6 cm).

ATTENTION: Potential Damage to Equipment. Be careful not to scrape the equipment against the cam lock of the door.

NOTES:

• Remove rubber feet from the bottom of any equipment you are mounting using rack ears.

• You can use custom rack shelves to mount equipment such as VCRs and DVD players in the 4U enclosure (Extron does not supply these shelves).

4. Attach power and AV cables to all equipment.

5. Trim back any exposed cable shields (braids or foil) or insulate them with heat shrink.

ATTENTION: Potential Damage to Equipment. To prevent short circuits, cut back the outer foil shield to the point where the cable exits a cable clamp. Both braided and foil shields should be connected to an equipment ground at the other end of the cable.

6. Secure the equipment in the rack by doing one or both of the following:

• Attaching one or both of the clamp brackets removed earlier

NOTE: Do not tighten the clamps or screws completely until you have tested the installation and made any needed adjustments to the cabling or switch settings.

7. Replace the top of the enclosure and use the four screws you removed in step 1 to reattach it.

Testing the Installation

Test the installation as follows:

1. Supply power to all input and output devices, the host computer, and so on.

2. Test all equipment, connections, and devices. Make adjustments to wiring, switch settings, and so on, as needed.

Completing the Installation

After you have pretested the installation and made any necessary adjustments, you can secure all equipment in the MLM-WB+.

1. Secure the equipment in the 4U rack enclosure by completely tightening the clamps or rack mounting screws.

2. Using cable ties, secure all power and AV cables to the cable guide behind the 4U rack enclosure (cut off any excess cable tie that protrudes). This provides strain relief as you open and close the door.

3. Replace the left and right side panels. Hand tighten the nuts that hold each side panel in place.

NOTE: Do not overtighten the nuts.

4. Completely tighten the mounting screws for the faceplates or rack shelves in the 2U rack enclosure.

1. Remove the nut, washer, and cam and set them aside.

2. Remove the cam, flip it over, and then thread it back onto the screw.

3. Replace the cam, washer, and nut and tighten securely.
