DEWE2-PA7 • Technical Reference Manual • Printing version 1.0.1 • February 15, 2018

MAIN SYSTEM

Cooling considerations

The intake vent of the DEWE2-PA7 is on the bottom of the chassis, where the cooling exhaust vent for the DEWE2-PA7 

is on the rear of the chassis.  

CAUTION: 

Adequate clearance between the chassis and surrounding equipment or blockages must   

 

 

 

be maintained to ensure proper cooling of the chassis power supply as well as the modules  

 

 

 

plugged into the chassis! 

NOTE:   

When installing the DEWE2-PA7 into a 19" cabinet please keep in mind that the unit is    

 

 

 

siphoning air from the bottom (see schematic above). Due to this circumstances  

 

 

5 u are required for one system (4 u =  1 u = cooling)! Otherwise the system  

 

 

 

 

may overheat and could get damaged!

System recovery

For more information regarding a total recovery please refer to the corresponding total recovery technical reference
