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).
