Mounting Considerations for GMC
and GMC Turbo Systems
Consider the following when mounting 1394 GMC and GMC Turbo
Systems.
Mounting GMC and GMC Turbo Systems Next to Flex I/O
   
Separating low voltage communication wiring from high voltage
power cables reduces the levels of EMI and RFI. Because high
voltage motor wiring is present at the bottom of each axis module we
recommend that you mount your Flex I/O modules to the left of the
system module.
