• When mounting the equipment inside a rack, fully address the concerns below. For the rack
mounting metal fittings, see Subsection 1.6.2 Installation (b), "Rack mount."
• 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 must be given to installing the equipment in an environment compatible with the
maximum ambient temperature specified in Subsection 1.6.1 Environment.
• Reduced Air Flow: Installation of the equipment in a rack must 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 must be such that a hazardous
condition is not achieved due to uneven mechanical loading.
• Circuit Overloading: Consideration must 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 must
be used when addressing this concern.
• Reliable Earthing: Reliable earthing of rack-mounted equipment must be maintained.
Particular attention must be given to supply connections other than direct connections to the
branch circuit (e.g., use of power strips).
