11.12 Power Unit Energization Setting

The power consumption can be decreased by decreasing the number of the power units in
operation according to the load capacity. Each power unit can be enabled (energized)/disabled (not
energized) separately. For the polyphase system, match the number of energized power units for
each phase.
