3.1 Pre-Wiring Instructions

3.1.1 Terminal connection diagram

The following shows the wiring of all terminals. After confirming the function of
each terminal, wire necessary terminals according to your application. When the
Parameter unit is used to perform operation, merely doing the main circuit wiring
enables the motor to run.

*This resistor is not needed when you use the
parameter unit (FR-PU04) to make calibration. This
resistor is used when you need to calibrate the meter
nearby because the meter is at a remote location, for
example. Note that when you connect the calibration
resistor, the meter may not deflect to the full scale. In
this case, use the parameter unit with the resistor to
make calibration.
