Figure 30: Powering FX15 I/Os
In order to maintain the insulation between the FX15 power supply and
the I/Os, run the power supply cable respecting the polarity as shown in
Figure 30, adding an External Protection fuse (2 A) to avoid mis-wiring.
IMPORTANT: Not respecting the power supply polarity will result in a short
circuit causing the blowing of the external fuse.
