SIP User's Manual 3. Installing the MediaPack
Rack Mount Safety Instructions (UL)
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.
Appropriate consideration of equipment nameplate ratings should be
used when addressing this concern.
•
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.)
