Connect The Power Cables - ABB ACSM1-04 Kurzanleitung

Check the insulation of the input and motor cables and
the motor
1. Check the insulation of the input cable according to local regulations before
connecting it to the drive.
2. Check the insulation of the motor cable and motor when the cable is disconnected
from the drive.
3. Measure the insulation resistance between each phase conductor and the Protective
Earth conductor using a measuring voltage of 500 V DC. The insulation resistance of
an ABB motor must exceed 100 Mohm (reference value at 25 °C or 77 °F). For the
insulation resistance of other motors, please consult the manufacturer's instructions.
Note: Moisture inside the motor casing will reduce the insulation resistance. If
moisture is suspected, dry the motor and repeat the measurement.

1. Lead the input cables into the inside of the cabinet. Ground the cable shield 360° at
the lead-through plate.
2. Twist the cable shields of the input cables into bundles and connect them and any
separate ground conductors or cables to the PE (ground) terminal of the input power
cabling panel.
3. Connect the phase conductors of the input cables to terminals U1, V1 and W1.
4. Lead the motor cables into the inside of the cabinet. Ground the cable shield 360° at
the lead-through plate.
5. Twist the cable shields of the motor cables into bundles and connect them and any
separate ground conductors or cables to the PE (ground) terminal.
6. Connect the phase conductors of the motor cables to terminals U2, V2, W2.
