3.1 Pre-Wiring Instructions
3.1.1 Terminal connection diagram
The following shows the wiring of all terminals (when sink logic is used). After confirming the
function of each terminal, wire necessary terminals according to your application. When the
operation panel 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 operation
panel (FR-DU04) or 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 operation panel or
parameter unit with the resistor to make calibration.
