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. Correctly wire the start/stop and safety circuits before you
energize the drive. If you momentarily close a digital input terminal, it can start a drive that is programmed for 3-
Wire control and cause serious injury or death from moving equipment.
WARNING
Fire Hazard. Install sufficient branch circuit short circuit protection as specified by
applicable codes and this manual. The drive is suited for circuits that supply not more than 31,000 RMS
symmetrical amperes, 240 Vac maximum (200 V Class), 480 Vac maximum (400 V Class). 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. Failure to obey can cause incorrect control circuit
operation.
