Rack shelf mounting
UL rack mounting guidelines
The following Underwriters Laboratories (UL) guidelines
pertain to the safe installation of the VSW 2VGA A in a rack.
1.
Elevated operating ambient temperature — If 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 switcher
in an environment compatible with the maximum ambient
temperature (Tma = +122° F, +50° 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.
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).
