Rack-mountable:

1. 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 a

environment compatible with the manufacturer’s maximum rated ambient temperature (Tmra).

2. 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,

3. Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous

condition is not achieved due to uneven mechanical loading.

4. 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.

5. 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.
