5.1.2 Block diagram
Note: 1.Keep terminals R1, S1 of the high power factor converter unconnected.
2.Except the FR-E500 and A024 series.
3.The parameter unit need not be used for calibration.
This resistor is used for calibration of a remotely located frequency
meter. Note that the needle of the frequency meter may not deflect to
fullscale when the calibration resistor is connected. In this case, use
both the resistor and parameter unit to make calibration.
4.The R, S, T terminals of the high power factor converter (FR-HC) must
be connected to the power supply.
Running the inverter without connecting the terminals to the power
supply will damage the high power factor converter (FR-HC).
