The CGS391 is a utility PCB to ease
the task of installing multiple CGS PCBs in to
a boat.
The CGS391's are normally mounted in
the bottom of a boat although it could also be
mounted on the rear of a front panel using
suitably tall spacers (typically at least
15mm) and the inclusion for 4 or 6 mounting
holes in the front panel (the use of hinged
stand-offs on one of the CGS391's would assist
with allowing easier access to the underside
of the PCBs and the panel wiring).
The CGS391 has mounting points and
power outlets for 16x 1" PCBs and comfortably
accepts 2", 3" (and wider) PCBs as required.
Power cables to the modules are hard-wired at
the CGS391 end and are normally terminated
with MTA-style connectors at the module end.
We recommend assigning one of the
CGS391 PCBs for 'analogue power' and the other
for digital or dirty power". This allows each
power circuit to have a separate 0V return to
a common node at the main power supply and so
help reduce noise pollution. Modules are
assessed as being either 'analogue' or
'digital' and then connected to the
appropriate CGS391. Readers should view the BoCGS and Voltron
unit power wiring diagrams for examples of
this application of the CGS391.
Two are required for each
installation.
