So in the example above the cabinet power must provide 540 mA at +12V and 300 mA at
-12V. If the cabinet is not capable of providing the necessary current, you should not install
the DELTA CEP A.
The Eurorack Standard has a 16 wire bus with pin headers. In the picture below you can
see a typical boxed 16 pin header but unfortunately it is not used by all manufacturers and
the Doepfer Technical Documents even suggests that only unboxed pin headers be used.
In our opinion most modules have been destroyed so far, because no protection against
misplaced sockets exists on most modules and bus systems.
The good thing about such a shrouded header is that you can connect the socket of ribbon
cable only in one direction with the plug. In fact, boxes have a "nose" that has to be
inserted into the slot seen above - and of course this only works if it is correctly aligned. But
even more important - the sensitive pins of the pin header are protected with the help of the
box against mechanical stress. On "crooked" follows quickly "off", if you have to straight out
the pins again. Now take the supplied ribbon cable and plug it into the 16 pin base of the
DELTA CEP A board. The boxed 16-pin header is easy to identify and is equipped with the
"POWER" label for the sake of simplicity.
Now take a look at the power supply circuit board of the Eurorack cabinet and the supplied
power cable of the DELTA CEP A. The power cable has 16 wires and a color marking on
the first wire (usually blue or red). On the bus board in a Eurorack cabinet, the first two
contacts carry -12V. Please make sure that the first wire with the color marking is always
connected to the -12 volt side of the pin headers. Also make sure that the cable is not
pushed to the right, left, up or down. Unfortunately, the Doepfer bus system has no reverse
polarity protection so please be extra careful at this step
