Notes on Rackmount Rails

When installing the rackmount kit (optional), please pay attention to the
following:

1. Elevated Operating Ambient - 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
maximum ambient temperature (Tma) specified by the manufacturer.

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 the circuits might have on overcurrent 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 (e.g. use
of power strips).”
