Rack Installation (Cont.)
Rack-mount Considerations
A. 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 (see Specifications information in this document).
B. 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. To ventilate the system normally and
avoid overheating, leave at least 1 inch (2.5 cm) on each side (including top and bottom) of
the OAT100R. Do NOT stack other equipment on the top of the OAT100R. Also, if multiple
OAT100R units are to be installed in close proximity, for example, in one rack, ensure that the
units’ AC power adapters are never stacked or bundled. Each adapter should have adequate
ventilation and should be isolated from other heat sources.
C. 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.
D. Reliable Earthing
Maintain reliable earthing of rack-mounted equipment. Particular attention should be given to
supply connections other than direct connections to the branch circuit (e.g., use of power strips).
E. Mains Outlet Earthing
The apparatus with Class I construction must be connected to a mains socket outlet with a
protective earthing connection.
