High power ship station installation (24 volt)
Where cables must pass through bulkheads with sharp edges,
the insulation of the cables should be protected by grommets.
Holes in the bulkhead need only be large enough to allow the
end of the cable with the smaller connector to pass through
(for example, the control cable between the control head and
the transceiver).
If the power and control cables are long and follow a common
path, keep the cables separated by at least 200mm. The cables
can be closer together for short distances, for example, to pass
through the same hole in the bulkhead.
Failure to observe this warning can cause distortion of the
transmitted audio signals.
