Attention – when the product is installed
in a rack:
• Elevated operating ambient temperature
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
manufacturer’s maximum rated ambient temperature of
0 to 45°C (Tmra).
• 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 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).
