3. Mechanical loading — Mount the equipment in the rack
so that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the
supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this
concern.
5. Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).
Rack mounting procedure
To mount the distribution amplifier on a 6" deep or 9.5" deep
rack shelf,
1. If rubber feet were previously attached to the bottom of
the unit, remove them.
2. Mount the unit on the rack shelf, using two 4-40 x 3/16"
screws in opposite (diagonal) corners to secure it.
3. Install blank panel(s) or other unit(s) on the rack shelf.
4. Attach the rack shelf to the rack using the supplied bolts.

DA, and place the unit in the desired location.
Rack mounting
UL rack mounting requirements
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the equipment in a rack.
1. Elevated operating ambient temperature — If the
equipment is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack
environment may be greater than room ambient
temperature. Therefore, install the equipment in an
environment compatible with the maximum ambient
temperature (Tma = +113 °F, +45 °C) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that
the amount of air flow required for safe operation of the
equipment is not compromised.
