UL Warning
a) 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. Therefore, consideration should be given to installing the equipment in an
environment compatible with the manufacturer's maximum rated ambient temperature
(Tmra).
b) Reduced Air Flow- Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
c) Mechanical Loading- mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
d) Circuit Overloading- Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of circuits might have on
over current protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
e) Reliable Earthing- Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).
