1.3 Environmental Use Information
A. Elevated operating ambient temperature - if installed in a closed or multiunit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra.
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. Additional space between
unit may be required.
C. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition
does not exist due to uneven weight distribution.
D. Circuit Overloading - Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of circuits could have on over current protection and
supply wiring. Appropriate consideration of equipment name plate rating should be used, when
addressing this concern.
E. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
F. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED
prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS
emission problems.
