Now join the free end of the ribbon cable (see
2
in
Fig. 3) to the nearest available position on the
system bus board (see
1
in Fig. 3).
A
Check very carefully that it is connected so
that the coloured marking on the ribbon
cable is at the bottom of the bus connector
(see
3
in Fig. 3), and it is pushed fully
home, not at a slight angle. Failure to
check this may result in the module’s instant
destruction as soon as the power is turned
back on!

When you’re installing extra modules, it may
be necessary to take another module or two
out, to allow you easier access to the bus
board.
D
Place the module carefully into the space in the
rack, and fasten it firmly in place with the supplied
screws. Put back any covers or blanking plates,
and screw them in firmly.

Now plug the system A-100 back into the main
power supply, and switch it on.

Test out the newly installed module.
If it doesn’t seem to be working as expected, im-
mediately disconnect the system from the power
supply again.
