Notes
------------------------------------------------------------------------------------------------------------
 The maximum current, current monitor gain, current measurement full scale, and the power
measurement full scale are set to the values corresponding to the rated output power which is
determined by the number of power units to be energized. However, the applied current
measurement accuracy and the power measurement accuracy are the values under the
condition where all power units are enabled for energization.
 If the number of the energized power units is changed, the setting values of the peak current
limiter and the RMS current limiter are restored to the factory default settings corresponding to
the rated power which is determined by the number of the power units to be energized.
 If you select [OK] without changing the energization settings in the power unit energization
setting window, the energization settings of all power units are disabled once and enabled
again. The setting values of the peak current limiter and the RMS current limiter are restored
to the factory default settings corresponding to the rated power which is determined by the
number of the power units to be energized.
 For the polyphase output, the number of power units on which the energization is enabled must
be same on all phases.
 If a failure occurs in a power unit for some reason, you can disable the energization for that
unit to restart using this product with the remaining power units. For details, see
9.1.3 .
 Power Unit Energization Setting cannot be changed for the polyphase output of DP060LM /
DP180LM because each phase is the minimum unit.
