9701-VWSB100AZHM Two grounding conductors. Use two conductors, if the cross-section of grounding conductor is less than 10 mm2 Cu or 16 mm2 Al (IEC/EN 61800-5-1). For example, use the cable shield in addition to the fourth conductor. b. Separate grounding cable (line side). Use it if the conductivity of the fourth conductor or shield is not sufficient for the protective grounding. c. Separate grounding cable (motor side). Use it if the conductivity of the shield is not sufficient for the protective grounding, or there is no symmetrically constructed grounding conductor in the cable. d. 360-degree grounding of the cable shield. Required for the motor cable and brake resistor cable, recommended for the input power cable. d b c a d Electrical installation 61 Connection procedure WARNING! Obey the instructions in chapter Safety instructions on page 13. If you ignore them, injury or death, or damage to the equipment can occur. WARNING! If the drive is connected to an IT (non-grounded) system or to a corner-grounded TN system, disconnect the EMC filter grounding screw. If the drive is connected to an IT (non-grounded) system, disconnect the varistor grounding screw. Before you start the work, stop the drive and do the steps in Precautions before electrical work on page 15. For information on cable routing, refer to Routing the cables on page 52. 1. Strip the motor cable. 2. Ground the motor cable shield under the grounding clamp. 3. Twist the motor cable shield into a bundle, put yellow-green insulation tape on it, fit a cable lug, and connect it to the grounding terminal. 4. Connect the phase conductors of the motor cable to the T1/U, T2/V and T3/W motor terminals. Torque the terminals to 1 N·m (0.7 lbf·ft). 5. If it is applicable, connect the brake resistor cable to the R- and UDC+ terminals. Torque the terminals to 1 N·m (0.7 lbf·ft). Use a shielded cable and ground the shield under the grounding clamp. 6. Strip the input power cable. 7. If the input power cable has a shield, twist it into a bundle, put yellow-green insulation tape on it, fit a cable lug, and connect it to the grounding terminal. 8. Connect the PE conductor of the input power cable to the grounding terminal. 9. If the combined cross-sectional area of the cable shield and PE conductor is not sufficient, use an additional PE conductor. 10. Connect the phase conductors of the input power cable to the L1, L2 and L3 input terminals. Torque the terminals to 1 N·m (0.7 lbf·ft). 11. Mechanically attach all of the cables on the outside of the drive. 62 Electrical installation Connecting the control cables Before you connect the control cables, make sure that all option modules are installed. Refer to Default I/O connection diagram (ABB standard macro) on page 63 for the default I/O connections of the ABB standard macro. For other macros, refer to the ACS380 Firmware manual (3AXD50000029275 [English]). Connect the cables as shown in Control cable connection procedure on page 66. WARNING! Obey the instructions in chapter Safety instructions on page 13. If you ignore them, injury or death, or damage to the equipment can occur. Before you start the work, stop the drive and do the steps in section Precautions before electrical work on page 15. Remove the front cover.
