Rack Mounting 

The PX200 can be installed in a 19-inch x 2U rack space using the single unit rack kit 
(order code: SingleRackKit-2U).  

Two amplifiers can also be installed in a side-by-side configuration using the double unit rack kit 
(order code: DoubleRackKit-2U). The double rack kit is assembled in the factory and includes coupling 
screws for the enclosure, the same handles as the single rack kit, and  
 

 

Figure 9. Single rack kit, showing the amplifier on left, and the rack adaptor on right.
