the factory for repair.
Tighten the terminal screws with the torque listed in the user manual.
Make sure the wiring is correct.
Replace the broken part of the cable.
Check setting for Pr. 06-50 (Time for Input Phase Loss Detection) and Pr. 06-52
(Ripple of Input Phase Loss).
Check the status of 3-phase power.
