Only trained service personnel should be used to remove the enclosure
from the pallet. Also, be sure you have a su󰀩cient number of service
personnel. Do not attempt to move enclosures by yourself.
Only UL® Listed ITE (Information Technology Equipment) units should
be installed inside the Great Lakes Wall Mount.
Be sure to read and follow all individual manufacturer equipment
manuals for safety and installation instructions.
Proper spacing is required when installing electrical equipment to avoid
electrical shock. Maintain minimum spacing between the accessories
and components and the computer enclosure assembly for safe
operation of the equipment when installed in accordance with the
National Electrical Code ANSI/NFPA 70-1999.
The ambient temperature operating range for the Great Lakes Wall
Mount and accessories is +50 to +95° F (+10 to +35° C).

INSTALLATION
Receiving and Unpacking
Inspect and report any damage before receiving. Unpack the wall
mount by carefully removing the corrugated carton and corners. Avoid
damaging the wall mount when removing packaging.
WARNING: Only trained service personnel should be used to unpack
and move the enclosure. Also, be sure you have a su󰀩cient 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 oor surfaces may cause the enclosure to topple over.
MOUNTING INSTRUCTIONS
Wood Studded Wall
Once the location on the wall has been determined, inspect the wall
surface. The wall must be at and square in the horizontal and vertical
plane to ensure the Great Lakes Wall Mount closes correctly. If the wall
is not at and square, the use of shims may be required.
Wood studded wall mounting instructions apply to a 2" x 4" wood stud
wall with 3/4" plywood.
Recommended Mounting Hardware for Wood Studded Wall
For WM, WE, and 15WM Series:
Qty (4) 3/8 x 2" long Lag Bolts and 1" O.D. Flat Washer
For WMCM, WDX and NEMA 12K Series:
Qty (4) 3/8 x 2 1/2" long Lag Bolts and 1" O.D. Flat Washer
Masonry Wall Surface- For masonry wall surface, the installer must
provide all the appropriate hardware.
PROTECTIVE GROUNDING
Protective grounding studs are provided along with grounding jumper
wires that electrically bond the enclosure doors to the enclosure frame.

WARNING: To avoid injury to persons or loss of life, ground each
enclosure individually to the dedicated branch circuit ground.
Connecting Main Protective Grounding Stud to the Dedicated
Branch Circuit Ground- Connect the dedicated branch circuit ground
connector to the main protective grounding stud located inside on the
back of the rear section on the WMCM, WM, WDX, WE and inside on
the side of the 15WM Series using a listed ring or closed-loop terminal.
Connecting Main Protective Grounding Stud to the Protective
Bonding Conductors- Connect the middle wall mount frame on the
WS, WM and WD Series to the main protective grounding stud located
inside on the back of the rear section using a listed ring or closed-loop
terminal. Connect the wall mount frame on the WE and 15WM Series
to the main protective grounding stud located inside on the back of
the rear section on the WE Series and inside on the side of the 15WM
Series using a listed ring or closed-loop terminal. Connect the front
door to the grounding stud located inside at the side of the wall mount
frame using a listed ring or closed-loop terminal.
Parts Not Bonded to Protective Earthing Terminal- The following
parts are not e󰀨ectively bonded to the protective earthing terminal: rails.
If these parts need to be bonded to the protective earthing terminal, do
