2.3  Mechanical Installation 
The Asterion DC Series power source is designed for rackmount applications, there is 
an  option  for  a  rack  mounted  slide.  Rack  mounting  requires  installing  the  flange 
brackets with handles to the side of the chassis: using M4-0.7 x 6 mm Philips flat-head 
screws to mount the brackets to the chassis, and # 8-32 Philips flat-head screws to 
mount the handles to the brackets. 
The unit is forced-air cooled with internal fans drawing air in from the front and sides 
and  exhausting at  the rear.   The front  and rear of  the unit  must be  kept clear  of 
obstruction and clearance must be maintained to allow unimpeded airflow. The same 
consideration given to the side grilles will minimize internal temperature rise. Special 
consideration  must  be  made  to  overall  air  flow  characteristics,  and  the  resultant 
internal  heat  rise,  when  a  source  is  installed  inside  enclosed  cabinets  to  avoid 
excessive heating and over-temperature problems. The temperature of the ambient 
air at the air intake should not exceed 50°C.
