CAUTION Electrical Component Sensitivity
When installing the chassis in a rack, be sure to implement the following Safety
instructions recommended by Underwriters Laboratories:
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.
Reduced Air Flow - Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation on 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 circuits might
have on overcurrent protection and supply wiring. Appropri-ate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Grounding - Reliable grounding 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.)
To attach the device to a 19-inch rack, follow these steps:
1 Position the device in your 19-inch rack and align the left-hand and right-hand bracket
holes to holes (of your choosing) in the vertical tracks of the 19-inch rack.
