4.2.1 4.2.1 Elevated Operating AmbientElevated Operating Ambient
If you install the unit in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, take care to install the equipment in an environment compatible with the
maximum ambient temperature (TMA).
4.2.2 4.2.2 Reduced Air FlowReduced Air Flow
Installation of the equipment in a rack should be such that the amount of air ow required for safe operation of the
equipment is not compromised.
4.2.3 4.2.3 Mechanical LoadingMechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven
mechanical loading.
4.2.4 4.2.4 Circuit OverloadingCircuit Overloading
Give consideration to the connection of the equipment to the supply circuit and the e󰀨ect that overloading of the circuits
might have on overcurrent protection and supply wiring. Use appropriate consideration for equipment nameplate ratings
when addressing this concern.
4.2.5 4.2.5 Reliable EarthingReliable Earthing
Maintain reliable earthing of rack-mounted equipment. Pay particular attention to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).
