• The enclosure is extremely heavy. Use caution when handling the enclosure. Do not attempt to unpack, move or install it
unassisted. Use a mechanical device such as a forklift or pallet jack to move the enclosure in the shipping container.
• Do not place any object on the enclosure, especially containers of liquid, and do not attempt to stack the enclosures.
• Inspect the shipping container and the enclosure for shipping damage. Do not use the enclosure if it is damaged.
• Leave the enclosure in the shipping container until it has been moved as close to the final installation location as possible.
• Leave adequate space at the front, rear, top and bottom of the enclosure for proper ventilation. Do not block, cover or insert
objects into the external ventilation openings of the enclosure.
• For permanent wall mounting, be sure to securely fasten the enclosure to the building structure before operation.
• Use caution when cutting packing materials. The enclosure could be scratched, causing damage not covered by the warranty.
• Save all packing materials for later use. Repacking and shipping the enclosure without the original packing materials may
cause product damage that will void the warranty.
• Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause the
failure of the life support equipment or to significantly affect its safety or effectiveness is not recommended.
• This enclosure supports a maximum Conduit Trade Size 2 with a 2.5 inch hole.
• Use only NEMA 3R (or higher) rated conduit/fittings to maintain the enclosure’s environmental protection rating.
Swinging wall-mounted NEMA 3R enclosures accommodate all standard 19-inch rack-mount equipment, regardless of vendor,
and ship fully assembled for quick and easy deployment. They have a NEMA 3R rating for protection against falling dirt, rain,
sleet, snow, windblown dust, splashing water and external formation of ice. They feature adaptable, heavy-duty cabinets in various
heights. All models have a hinged design that lets the cabinet swing away from the wall bracket for easy equipment access.
Swinging wall-mounted NEMA 3R enclosures have variable mounting depths, ideal for servers. The cabinets include a lockable,
removable front door and hinged swing cabinet body for convenient maintenance.

4.1 Preparation
The enclosure must be installed in a structually sound area that is able to bear the weight of the enclosure, all the equipment
that will be installed in the enclosure and any other enclosures and/or equipment that will be installed nearby. Before
unpacking the enclosure, you should transport the shipping container closer to the final installation location to minimize the
distance you will need to move the unit after the protective packaging has been removed. If you plan to store the enclosure for
an extended period before installation, follow the instructions in the Storage and Service section.
4.2 Unpacking
You need several tools:
• Level
• Phillips-head screwdriver
• Appropriate tools for wall mounting
You also need the following hardware:
• Appropriate hardware for wall mounting (not included)
1Move shipping pallet to a firm, level surface.
2Open box and remove the four foam corner protectors. Save all packing materials for later use unless you are certain
they will not be required. Packing materials are recyclable.
3With one person on each side, carefully lift the enclosure out of the box and place on a firm, level surface.
4Examine the enclosure for any damage or loose parts. Confirm all parts are present. If anything is missing or damaged,
contact Tripp Lite for assistance. Do not attempt to use the enclosure if it has been damaged.
4. Enclosure Installation
Caution! Read All Instructions and Warnings Before Installation!
Warning: Rack enclosures can be extremely heavy. Do not attempt to unpack, move or install the enclosure
without assistance. Use extreme caution when handling the enclosure and be sure to follow all handling and
installation instructions. Do not attempt to install equipment without first stabilizing the enclosure.
Use at least two people to unpack the enclosure.
Never extend more than one component from the enclosure at a time.
Warning: Never attempt to lift or install without adequate help.
Do not try lifting the enclosure alone.

4.3 Ground Connection
All parts of the enclosure are grounded to the frame of the enclosure.
Use the enclosure’s rear threaded grounding point Aand an M6 hex nut
and washer (included) to connect the frame of the enclosure directly to
your facility’s earth ground connection with an 8 AWG (3.264 mm) wire.
Route the ground wire under the enclosure’s frame to ensure unhindered
door operation. Warning: Attach each enclosure to earth ground
separately. Do not use the enclosure without an earth ground
connection.

5. Enclosure Configuration
Before installation, be sure to plan the location and arrangement of components within the enclosure. Be sure all mounting
rails are reversed or adjusted for depth, depending on your equipment configuration.
5.1 Door Locks
The front and rear doors have locks that can be opened with the included keys.
5.2 Cable Access and Management
The enclosure has an opening for cable access and management. The opening
can be closed by screwing in the removable cable access panel.

5.3 Mounting Rails
The enclosure comes with mounting rails that have tapped holes for mounting rack
equipment. To install equipment, use the included hardware. Warning: Be sure to
have the enclosure securely mounted to the wall, or in its final position on
the floor, before mounting any equipment inside. Also be sure to have all
the right adjustments on your rails before mounting equipment. (See below
for Adjusting Mounting Rail Depth.)
5.4 Adjusting Mounting Rail Depth
Warning: Do not attempt to adjust rails while equipment is installed in the enclosure. Do not attempt to use rails
without screws installed. (2 per rail.)
The preset mounting depth varies based on the model. Do not adjust the mounting rails unless your equipment requires a
different mounting depth. The front set of rails can be adjusted independently in 1/2 inch (12.7 mm) increments.
1Each equipment mounting rail is connected to the enclosure with 2 screws: one in the upper corner and another in the
lower corner. Using a Phillips-head screwdriver, remove the screws that fasten the rails to the enclosure.
2Slide the mounting rails to the desired depth and reattach them using the screws you removed in Step 1.

1. Mount the enclosure to wall studs
Warning: Never attempt to lift or install without adequate help.
Do not try lifting the enclosure alone.
Do not attempt to mount the enclosure to the wall with equipment in the enclosure.
The supporting surface must be able to safely support the combined load of the equipment
and all attached hardware and components. For the actual weight, size and load capacity of
the enclosure, view the product specifications and other support resources at
tripplite.com/support.
• Enclosure must be installed by a qualified technician. Before mounting, use a level and tape measure to position your
mounting area precisely. Use a minimum of four screws (not included, sizes will vary by model) to secure the enclosure in
place. A fender washer with close cell foam is provided with the cabinet. The close cell foam side of the washer should be
against the cabinet to seal the mounting hole.
• Make sure mounting screws are anchored into the center of the studs. Use of a stud finder is highly recommended.
• If there is no stud at the mounting location, it is recommended you install studs at the desired location to secure the
enclosure in place. Do NOT use plastic expansion wall anchors, threaded drywall anchors, threaded drywall toggles,
sleeve-type hollow wall anchors (a.k.a. molly bolts) or toggle bolts, due to the weight of the enclosure.
• Use suitable mounting means when installing to cinder block, concrete or wood studs. It is the installer’s responsibility to
choose suitable mounting hardware (not supplied). Do NOT use plastic expansion wall anchors, threaded drywall anchors,
threaded drywall toggles, sleeve-type hollow wall anchors (a.k.a. molly bolts) or toggle bolts, due to the weight of the
enclosure.
• If placing the enclosure over a telecommunications receptacle, remove the wall plate, then fasten the enclosure to the
wall. Once secured, fasten the wall plate over the receptacle.
• If no telecommunications receptacle is available, a surface mount box (or biscuit jack) and equipment cord can be
mounted inside the unit.
• Use an adhesive-backed surface mount box.

position your mounting area
precisely. Use appropriate
fasteners (not included) to
secure the enclosure to the wall.
A minimum of four fasteners is
recommended. A fender washer
with close cell foam is provided
with the cabinet. The close cell
foam side of the washer should
be against the cabinet to seal
the mounting hole. Use suitable
mounting means when installing
to cinder block, concrete,
drywall or wood studs. Warning:
The supporting surface must
be able to safely support the
combined load of the
equipment and all attached
hardware and components.

BMount the enclosure's back
door by itself to wall studs.
The number of hole cutouts
on the back door of the
enclosure will vary based on
your model. Each hole can
accommodate an M8, M10,
5/16” or 3/8” bolt. The holes
are centered 16” apart
horizontally to accommodate
the standard placement of
wall studs. The vertical
distance between the holes
will vary based on your
model.
Your model’s hole configuration
may be different.

7. Equipment Installation
Warning: Do not install equipment until you have stabilized the enclosure. Install heavier equipment first and
install it towards the bottom of the enclosure. Install equipment starting from the bottom of the enclosure and
proceeding toward the top of the enclosure—never the reverse. If using sliding equipment rails, be careful when
extending the rails. Do not extend more than one set of sliding equipment rails at one time. Avoid extending
sliding equipment rails near the top of the enclosure.
Note: The tapped holes in the middle of each rack unit are numbered and also include a small notch to aid identification. A single rack
unit includes the space occupied by the numbered hole and the holes directly above and below.
