Power Connection
The 902 VCA com es with the requi red power cable for c onnecting
to a standa rd Eurorack power su pply system. Fol low these steps
to connec t power to the module. It i s easier to make these
connec tions before the m odule has been moun ted into a
rack cas e.
1. Turn the power su pply or rack case p ower o and
disconne ct the power cabl e.
2. Insert the 16- pin connector o n the power cable into t he
socket on t he power supply or rac k case. The connec tor has
a tab that wi ll align with the gap in t he socket, so it can not
be inser ted incorrec tly. If the power supply d oes not have
a keyed socke t, be sure to orient pi n 1 (-12 V) with the
red str ipe on the cable.
3. Insert the 10 -pin connecto r into the socket on th e back of
the module. T he connector has a t ab that will align wi th the
socket for correct orientation.
4. After both en ds of the power cable hav e been securely
attac hed, you may mount the mo dule in a case and tur n on
the power supply.
Installation
The neces sary screws ar e included with th e module for mount ing
in a Eurorac k case. Connect t he power cable bef ore mounting.
Dependi ng on the rack case, th ere may be a series of x ed holes
spaced 2 HP ap art along the leng th of the case, or a tra ck that
allows indi vidual threaded p lates to slide along th e length
of the cas e. The free-movi ng threaded plate s allow precise
positio ning of the module, bu t each plate should be po sitioned in
the approx imate relation to th e mounting holes in yo ur module
before attaching the screws.
Hold the mo dule against the Eur orack rails so that e ach of the
mounting h oles are aligned wi th a threaded rail o r threaded plate.
Attach t he screws part w ay to start, whic h will allow small
adjustments to the positioning while you get them all aligned.
After th e nal position has b een establishe d, tighten the
screws d own.
