Note:cable lugs are needed in frame sizes R2 and R3.• Supply cable grounding: If shielded cable is used, and the conductivity of theshield is < 50% of the conductivity of the phase conductor, use a separate PEcable (1) or a cable with a grounding conductor (2). With shielded cable 360°grounding of the supply cables is recommended.Motor cable grounding: Use a separate grounding cable (3) if the conductivity ofthe cable shield is < 50% of the conductivity of the phase conductor and there isno symmetrically constructed grounding conductor in the cable (see Planning theelectrical installation: Selecting the power cables).360 degrees grounding is required at the cabinet entry in first environmentinstallations. First environment EMC compliance is defined in chapter Technicaldata.Note: If there is a symmetrically constructed grounding conductor in the motorcable in addition to the conductive shield, connect the grounding conductor to thegrounding terminal at the drive and motor ends.Note: Do not use an asymmetrically constructed motor cable. Connecting itsfourth conductor at the motor end increases bearing currents and causes extrawear.Electrical installation
