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 S76005, S7601 and S7602 (i.e. the assembly carrying the Amplifiers, Power Supplies, Controller,
Splitter/Drive Changeover and Combiner) are
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 Assembly 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 12U height (for the S76005 or
S7601) or 14U (for the S7602). 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
Assembly can then be refitted and external connections made.
