Basic Assembly Instructions.
One of the most important aspects of the case is making sure the bus boards
are well isolated from any other surface. A good way to do this is to use
standoffs to give them room for the wiring to be run below as well as ample
space between the board and any surface that could possibly impede its
performance. We recommend using standoffs with a minimum height of
8mm(.29”) when installing a Zeus Powered or Passive Bus Board.
The recommended screw size is #6. There are two aspects to the screw that
the builder must be aware of: 1) length of the screw and 2) diamater of the
screw head. The length is important because you don’t want it to surpass the
space available for it to fit all included parts snuggly, leaving the board loose
and moveable in the case. Secondly, the head diameter is important because
if it is too small it might possibly slip through the provided hole space.
Conversely, if it is too large it might touch important circuit contacts causing
a possible short and damaging your system. Lastly, plastic washers are always
a welcome addition for added isolation and protection for your bus boards.
Two very important aspects of the assembly are the gauge and polarity of the
wires. 18AWG is what we recommend you use to wire your system’s
connections. You will be dealing with four types of signals: +12V, -12V, 5V,
and GND. The power supply will have +12V and GND going into your Powered
Bus Board’s “IN” and “GND” input sockets. If you accidently connect these two
wires backwards you WILL damage your Powered Bus Board. We recommend
you use a Voltmeter to be absolutely sure you have the polarities correctly
identified. The same goes for all four wires coming from the Powered Bus
Board if you are connecting one or more Passive Bus Boards. The value
indicators for the flat terminal connectors are located on the back of the
Passive Bus Boards. Do not mistaken them for the Eurorack socket signal
indicators.
