NOTES When the power is turned OFF during the reset process, the cumulative pulse monitor value and
the cumulative pulse carrying overflow times are not stored in the EEPROM.
For storing the cumulative pulse monitor value and the cumulative pulse overflow times, in the
EEPROM at power OFF, connect R1/L11 with P/+, and S1/L21 with N/- so that the control power is
retained. When connecting the high power factor converter (FR-HC2) or the converter unit
(FR-CC2), assign the instantaneous power failure detection (X11) signal to an input terminal to
input the IPF signal from the FR-HC2/FR-CC2 to the terminal for X11 signal.
