Installation 
Ventilation 
To prevent overheating, do not operate this product in an area that 
exceeds the environmental temperature range listed in the table of 
specifications. Consider using forced air ventilation and/or incrementing 
the spacing between units to reduce overheating. Consideration must be 
given if installed in a closed or multi-unit rack assembly since the 
operating ambient temperature of the environment may be greater than 
the room ambient temperature. Contact with thermal insulating materials 
should be avoided on all sides of the unit. 
Placement 
Tips 
When installing a CEN-RFGW-EX near another CEN-RFGW-EX, for 
optimum performance, keep the following in mind: 
•  Do not place multiple gateways on the same channel. Refer to 
“Appendix A: The RF Spectrum” on page 30 for details. 
•  Gateways on adjacent channels should be at least 12 feet 
(3.7 meters) apart. 
•  Gateways on non-adjacent channels should be at least three feet 
(0.9 meters) apart. 
When installing a CEN-RFGW-EX near a Wi-Fi access point, for 
optimum performance, keep the following in mind: 
•  Gateways on RF channels adjacent to operating Wi-Fi channels 
should be placed at least 12 feet (3.7 meters) from the nearest 
Wi-Fi access point. 
•  Gateways on RF channels that are non-adjacent to Wi-Fi channels 
should be located at least six feet (1.8 meters) from the nearest Wi-
Fi access point. 
For more information on RF channels and their interaction with the 
Wi-Fi spectrum, refer to “Appendix A: The RF Spectrum” on page 30. 
For additional information on optimal gateway placement, refer to 
“Appendix B: Optimum RF Reception Guidelines” which starts on page 
31.
