4. Enclosure Installation
(continued)
4.6 Ground Connection
• All parts of the enclosure are grounded to the frame of the enclosure.
• Grounding studs have been provided in all four corners of the enclosure to allow for
grounding in any configuration (including front or back door reversals).
• Grounding holes are also provided on top and bottom corners of both front and back
doors to accommodate any configuration.
• To ground the enclosure simply connect the two quick-disconnect grounding wires, one
to the hole provided on the inside of either the front or back door and the other to the
stud provided in any corner of the enclosure. Connect your facility’s earth ground
connection to the grounding stud not used by door connections, using an 8 AWG
(3.264 mm) wire.
Warning: Attach each enclosure to earth ground separately. Do not use the
enclosure without an earth ground connection.
4.5 Leveling
1
After the enclosure has been moved to the installation location, use a carpenter's level to check
the slope of the floor. If the floor slopes more than 1%, choose an alternate installation site.
2
Use a 14 mm open-end wrench to lower each leveler
A
until it reaches the floor. (There are 4
levelers, 2 at the front and 2 at the rear.) Make sure each leveler contacts the floor solidly.
Note: Lower a leveler by turning it clockwise; raise a leveler by turning it counter-clockwise.
3
After lowering each leveler, use the carpenter's level to confirm that the enclosure is level in all
directions. Adjust the levelers as required until the enclosure is level.
WARNING: Level the enclosure before attempting to install equipment. Install the enclosure in a
structurally sound area with a level floor that is able to bear the weight of the enclosure, all
equipment that will be installed in the enclosure and any other enclosures and/or equipment that
will be installed nearby.
