2.1.2 Rack Mounting
If the Transmitter is not supplied ready mounted in a 19 inch rack, this will be required to be done at
time of installation.
! CAUTION !
The S79005 (i.e. the assembly carrying the Amplifiers, Power Supplies, Controller, Drive
Changeover/Output Monitor and Combiner) is heavy. Before installation in a rack, the Amplifier
Modules and Power Supplies should be removed to reduce the overall weight and ease the process.
These units are removed from the front of the Transmitter, taking care to release the mechanical
securing locks first. The Fan Assemblies may also be opened, unplugged and then removed from the
rear of the Transmitter.
The 19 inch rack should be of standard 600mm depth and at least 7U height. Additional height will be
required if Exciter/Drive(s) are to be fitted into the same rack (recommended). These should be fitted
below the actual Transmitter section for ease of inter-wiring. Additional bottom support ‘L’ brackets are
also be required at each side, below the Transmitter, to help carry its weight. The Transmitter is then
fixed to the front of the racking using eight screws, plastic cup washers and caged nuts. The Amplifier
modules, Power Supplies and Fan Assemblies can then be refitted and external connections made.
