NOTICE
Rack-mount instructions
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack, the operating
ambient temperature of the rack environment may be greater than the 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.
B) 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.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
D) 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.
E) 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).
