Appendix – C
Fitting the board to an enclosure
As previously stated this PCB is meant for development purposes only, however, it’s understood that in
certain circumstances there may be a requirement to turn this stand-alone PCB into a complete unit to
be part of an initial system test.
Enclosure
The PCB has been designed such that it can be accommodated into a standard extruded aluminium case
(
Hammond manufacturing 1455L1602
). This is not supplied as part of the kit, but may be purchased
from most electronic component suppliers.
There is a little spare room in this enclosure to accommodate further circuitry, however, if a much larger
volume is required the
Hammond Manufacturing
1457N1601
may be used. This gives about double the
height which should be more than adequate for a second PCB to be fitted.
The following pages provide some basic machining information to enable the ends of the case to be
machined in order to accommodate the PCB.

upon completion.
You will note that indicators such as ‘Overload and Power ON’ have
been omitted as the position of these may depend upon any other
circuitry that the user may wish to add.
