Power Settings
The power limit settings (parameter OP.Hi) for this model are voltage dependant. The
figures represent the maximum percentage of time that controlled power is supplied to
the elements. Do not attempt to “improve performance” by setting a value higher than
the recommended values. To adjust the parameter refer to the "Changing the
Maximum Output Power" of the control section of the manual.
