Electrical voltage
Incorrect wiring can cause unexpected states during the commissioning phase.
► Wiring must be complete and correct.
► Wiring must be free of short circuits and earth faults.
► The motor circuit conguraon (star/delta) must be adapted to the inverter.
► The motor must be connected in-phase (rotang direcon).
► The "emergency o" funcon of the overall system must operate correctly.
► Clear hazardous area.
► Observe safety instrucons and safety clearances.
Precondions
