94 Electrical installationConnecting the power cables Connection diagram1 For alternatives, see section Selecting the supply disconnecting device on page 59.2 Use a separate grounding PE cable (2a) or a cable with a separate PE conductor (2b)if the conductivity of the shield does not meet the requirements for the PE conductor(see page 69).3 360-degree grounding is recommended if shielded cable is used. Ground the other endof the input cable shield or PE conductor at the distribution board.4 360-degree grounding is required.5 External brake resistor6 Use a separate grounding cable if the shield does not meet the requirements ofIEC 61800-5-1 (see page 69) and there is no symmetrically constructed groundingconductor in the cable (see page 75).7 du/dt filter or sine filter (optional, see page 263).Note:If there is a symmetrically constructed grounding conductor on the motor cable in addition tothe conductive shield, connect the grounding conductor to the grounding terminal at the driveand motor ends.Do not use an asymmetrically constructed motor cable for motors above 30 kW (see page 69).Connecting its fourth conductor at the motor end increases bearing currents and causes extrawear.L1 L2 L3 T1/U T2/V T3/WUDC+R+ UDC-R-L1 L2 L3(PE) (PE)PEACS880-01PEU1V1 W13 ~ M12a2b356743
