If five or more system boards or five or more IO_Units are to be mounted,
two sets of the MC-57PS11/MCB57PS11 power supply units need to be
prepared.
When this option has not been prepared, a dummy component is mounted in
the relevant slot.
If dual power feed is used, the MC-57DP11/MCB57DP11 dual power feed
option needs to be prepared.
If more than one AC cable of the equipment is connected to the customer's
distribution panel, connect the AC cables to outlets independently using one
cable per power supply.
For information about the circuit breakers on the customer's distribution
panel, see Section 2.6, "Circuit Breaking Characteristics."
