General Mounting Recommendations

Elevated Operating Ambient Temperatures

If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environ-
ment may be greater than room ambient. Therefore, consideration should be given to installing the equip-
ment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.

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.

Mechanical Loading

Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to
uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the supply circuit and the effect that
overloading of the circuit might have on overcurrent protection and supply wiring. Appropriate consider-
ation of equipment nameplate ratings should be used when addressing this concern.

Reliable Earthing

Reliable earthing of rack-mount 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).
