SAFETY INSTRUCTIONS

Rack Installation
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 of 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. Appropriate consideration of equipment nameplate ratings
should be used when addressing this concern.
Reliable Earthling
Reliable earthling 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).
Indicates that improper use may cause fumes or fire.
Indicates that improper use may cause personal
injury due to high temperature.
Indicates a non-particular notice or warning.
Indicates the presence of laser beam that cause
blindness.
