For easy operation, the distribution board should be installed in the
same room as the Switch or in an adjacent room.
For a redundant power supply, the power from different power supply
systems can be supplied to each power supply unit.
Ensure that the capacity for incoming current to the distribution board
is greater than the operating current of the circuit breaker. If it is not,
the circuit breaker might not operate properly in the event of a failure,
which could result in fire.
