Rack Mounting

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of 
these products in a rack:

• 

Elevated operating ambient temperature — If the unit 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 = +122 °F, +50 °C) specified by Extron.

• 

Reduced air flow — Install the equipment in the rack so that safe operation and 
adequate air flow is provided to the unit.

• 

Mechanical loading — Mount the equipment in the rack so that a hazardous 
condition is not achieved due to uneven mechanical loading.

• 

Circuit overloading — Connect the equipment to the supply circuit and consider the 
effect that circuit overloading might have on overcurrent protection and supply wiring. 
Consider the equipment nameplate ratings when addressing this concern.

• 

Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted 
equipment. Pay particular attention to supply connections other than direct 
connections.
