Recommended External Fuses
External fuses should be chosen based upon the physical manifold configuration. Please refer to table
below for the fuse sizing chart.

The Node and Inputs Aux Power pins supply power to the node electronics. These pins must
be powered at all times for communication node and Inputs to be functional.
The internal electronic fuses exist to protect against damage due to catastrophic failure of
internal components. External fuses are always recommended for protection against power
supply failure, over-current conditions, etc…
