Selecting the capacity setting 'Option PCB'(Accessory) according to the capacity mentioned
below.
- The corresponding capacity setting 'Option PCB' needs to be selected depending on the
need capacity.
- After checking the need capacity, remove the 24 k Option PCB equipped in the main PCB,
and set up the Option PCB fitted the need capacity in the main PCB.
