3.2.2 Mounting and removing
The TWTA may be operated as a standalone benchtop unit, or it may be installed in a 19" rack.
If rack mounting of models provided with lifting handles is desired, one or more of the lifting handles may
need to be removed to clear the rack's front mounting rails. Optional slide rails for rack mounting are
available from Amplifier Research.

A TWO PERSON OPERATION
Before removing the amplifier from rack or benchtop cabinet, disconnect power, RF, and any other
interface connectors. On the rear of the unit, remove any screws used to connect brackets to amplifier.
On the front of the unit, remove the four screws holding the front panel to the cabinet. Carefully slide the
amplifier out of the front of the cabinet.

If bottom supports are used for rack mount installation of multiple units, the amplifiers should be
separated vertically by at least 1 3/4 inches. This will allow room for necessary support rails and
facilitate installation and removal of the units.
The use of chassis slides greatly simplifies rack mounting of multiple units. Figure 3-1 also shows the
location of holes used in mounting optional slide rails to the TWTA chassis.
