1.4 Installation
NOTES:
• Fuse holders, fuses, and circuit breakers are sold separately. See “1.6 Accessories” on page 12 for

1.4.1 Important Installation Guidelines
• Elevated Operating Ambient - If you install this product in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than room ambient. Therefore,
consider installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
• Reduced Air Flow - When you install this equipment in a rack, make sure you do not compromise the amount
of air flow required for safe operation of the equipment.
• Mechanical Loading - When you mount the equipment in the rack, make sure to keep the mechanical load
balanced to prevent a hazardous condition.
• Circuit Overloading - Pay attention 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. Appropriately consider
equipment nameplate ratings when addressing this concern.
• Reliable Earthing - Maintain reliable earthing of rack-mounted equipment. Pay particular attention to supply
connections other than direct connections to the branch circuit (e.g., use of power strips).
• Disconnect Device - Incorporate a readily available disconnect device into the building installation wiring.
