WARNING! Sudden Movement Hazard. Set the MFDI parameters before you close control circuit switches. Incorrect Run/Stop
circuit sequence settings can cause serious injury or death from moving equipment.
WARNING! Sudden Movement Hazard. Check the I/O signals and the external sequences for the drive before you set the
Application Preset function. When you set the Application Preset function (A1-06 ≠ 0), it changes the I/O terminal functions for the
drive and it can cause equipment to operate unusually. This can cause serious injury or death.
WARNING! Fire Hazard. Install sufficient branch circuit short circuit protection as specified by applicable codes and this manual.
The bypass is suitable for circuits that supply not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (208/240 V),
480 Vac maximum (480 V). Incorrect branch circuit short circuit protection can cause serious injury or death.
NOTICE: When the input voltage is 440 V or higher or the wiring distance is longer than 100 m (328 ft), make sure that the motor
insulation voltage is sufficient or use an inverter-duty motor or vector-duty motor with reinforced insulation. Motor winding and
insulation failure can occur.
Note:
Do not connect the AC control circuit ground to the drive enclosure. Incorrect ground wiring can cause the control circuit to operate
incorrectly.
