with the "-12V" printing on the bus board next to the pin header.
Check also very carefully that it is pushed fully home, not at a slight angle and
•
not vertically or horizontally displaced.
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.
Remove and install modules only with the AC/AC adapter disconnected from the A-

100MNT/MBP
(3) LEDs
The two LEDs indicate that the power supply is working properly. Once the A-100MNT/A-
100MBP is connected to the external AC/AC adapter, both LEDs should come on. The
upper LED is the indicator for +12V, the lower for – 12V.
If both LEDs don' t come on, first of all check that mains power is available at the socket
which the A-100MNT/A-100MBP power supply was connected to; then that the mains
adaptor is actually putting out voltages, and that a DC adaptor hasn' t been used by mistake
instead of the 12-15V AC type. If only one of the two control LED lights up probably by
mistake a power supply with DC output is used.
(4) Label (only A-100MNT version 2)
This label is used to identify version 2 of A-100MNT. If you own an A-100MNT without this
label it's probably version 1 that requires another AC/AC adapter (9V AC).
If the A-100MC is used please pay attention to these additional notes:
Move the mounting nuts inside the aluminium rails to positions that fit to the holes of
•
the module front panels. E.g. a small screwdriver or paper-clip may be used for it.
Place the module carefully into the space in the case, and fasten it firmly in place
•
with the supplied screws (M3x6).
Repeat this procedure until all modules (and possibly blind panels) are installed and
•
the front of the case is fully closed.
Now connect the A-100MC to the power supply
•
Test out the installed modules.
•
If it doesn' t seem to be working as expected, immediately disconnect the A-100MC
•
from the power supply.
In this case, double-check all connections, making completely sure that the ribbon
•
cables are the right way round where they connect to the bus.
Interconnecting modules
For connecting modules to each other, you need mono mini-jack ((∅ 3.5 mm) patch
leads. We offer patch leads in different lengths (from 15 cm to 2 m) and colors.
