Chapter 3: Mounting Instructions
3. Mounting Instructions
3.1 Receiving, Unpacking, and Removing the Elite Wallmount Enclosure from the Pallet
Inspect for damage and report damage if there is damage before receiving. Refer to Section 2.3 for what‘s included
in the package.
Unpack the enclosure by carefully removing the corrugated carton and corners. Avoid damaging the enclosure when removing
packaging.
WARNING: Only trained service personnel should be used to remove the enclosure from the pallet. Also be sure you have a
sufficient number of service personnel. Do not attempt to move enclosures by yourself.
WARNING: Be careful when moving enclosures before installation. Sudden stops and starts, excessive force, obstructed routes,
and uneven floor surfaces may cause the enclosure to topple over.
3.2 Mounting to Wood Stud Walls
Once a location for the cabinet has been selected, inspect the wall and ensure that the wall or other mounting surface has a
structural load capacity that will support the cabinet and the maximum payload. Ensure that the mounting surface extends
beyond the top, bottom, left, and right edges of the rear of the cabinet.
The rear frame must be secured to a wall using the hardware provided. For masonry, or mounting to other surfaces, the installer
must provide the appropriate hardware.
WARNING: Improper handling and use of the Elite Wallmount Enclosure could result in equipment damage, serious injury,
or possible death.
Other Wall Surfaces
For other wall types, the installer must provide appropriate hardware.

Chapter 4: Operation
4. Operation
4.1 Operating the Door
The Elite Enclosure is supplied with two locks (one for the front door and one to lock the middle section to the rear section).
The middle section and rear section incorporate a grabber catch that enables the middle section to be held shut without locking.
4.2 Removing or Installing a Door
Open the door beyond 90°, remove the top half of the upper hinge, then grasp the door with both hands and carefully lift it
upward. When the door is free of two hinge pins, pull the door away from the enclosure. To attach the door, align both door
hinges to their respective hinge pins on the enclosure and slowly slide the door down until seated.
4.3 Reversing a Door
The front and rear doors are installed with two hinges as standard from Black Box. Removing the hinges enables you to reverse
the door by flipping them over and reinstalling the hinges using the universal mounting holes. All the enclosure frames and doors
can be hinged right- or left-hand. The handle can be reversed along with the hinging. See Figure 4-1.
