tribution will ensure that a fault in any of the machines connected
to the unit that causes a short circuit only affects the line that is
faulty. The other connected loads will have guaranteed continuity

short circuit.
For parallel systems, the connections that go from each unit to the
board must be repeated.
Finally, once the input and output connections have been
made, replace the protective cover of the terminals as shown
