SAFETY SYMBOLS USED IN THIS MANUAL
This manual provides general safety guidelines to be observed during
installation, operation, and maintenance of the Swing Racks.
WARNING: Failure to follow directions in the warning could result in injury to
persons or loss of life.
CAUTION: Failure to follow directions in the caution could result in damage to
equipment or storage data.
SAFETY CONSIDERATIONS
WARNING: Improper handling and use of the Swing Racks could result in
equipment damage, serious injury, or possible death.
Only UL® Listed ITE (Information Technology Equipment) units should be
installed inside the Swing Rack.
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 Electric Code ANSI/
NFPA 70-1999.
The ambient temperature operating range for the Swing Racks and
accessories is +50 to +95°F (+10 to +35°C).
The non-operating temperature is -4 to +140°F (-20 to +60°C)

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 Swing Rack closes correctly. If the wall is not at and square, you might be
required to use shims.
Wood studded wall mounting instructions apply to a 2" x 4" wood stud wall
with 3/4" plywood.

When installing a Great Lakes Swing Rack or Wall Mount to materials such
as wood, cinder block, concrete, etc., please consider the load capacity
within the swing rack or wall mount structure, and be certain to check with
local authorities to determine the appropriate hardware requirements
for these conditions. Because wall compositions may vary at dierent
installation sites, Great Lakes cannot warrant the tness or suitability of
any installation instructions or installation hardware it may provide for
swing rack or wall mount enclosures. Great Lakes hereby DISCLAIMS
ALL WARRANTIES, EXPRESS AND IMPLIED, INCLUDING THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE, REGARDING THE SUFFICIENCY, FITNESS OR SUITABILITY OF
ANY INSTALLATION INSTRUCTIONS OR INSTALLATION HARDWARE
GREAT LAKES MAY PROVIDE FOR SWING RACKS AND WALL-MOUNTED
ENCLOSURES. Great Lakes recommends that an experienced maintenance
and/or technical person be consulted regarding the proper wall-mounting
hardware and procedures to be used for the anticipated load capacity of
the swing rack or wall mounted enclosure.
Product specications are subject to change without prior notice.
POWER
When using PDUs, each PDU should be connected to a committedbranch
circuit that is rated for the continuous load of all the equipment connected.
When not using a PDU, each piece of equipment should be connected to a
dedicated branch circuit.
PROTECTIVE EARTHING/GROUNDING
A main protective earthing stud is provided.
WARNING: To avoid injury to persons or loss of life, ground each Swing Rack
individually to the dedicated branch circuit earthing ground
CONNECTING MAIN PROTECTIVE EARTHING STUD TO THE DEDICATE D
BRANCH CIRCUIT EARTHING GROUND CONDUCTOR
Connect the dedicated branch circuit earthing ground conductor to the main
protective earthing stud located on the support frame using a listed ring or
closed-loop terminal.
