3.0 Environmental Use Information

ARack-Mounting - To mount this equipment in a rack, please refer to the installation instructions 

located in the user manual furnished by the manufacturer of your equipment rack.

B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition 

does not exist due to uneven weight distribution.

CElevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly, 

the operating ambient temperature of the rack may be greater than room ambient temperature.  
Therefore, consideration should be given to Tmra.

D. 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 units 
may be required.

E. 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.

F. 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).

G. 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.
