Check the insulation of the motor cable and motor when the cable is disconnected
from the drive, see figure
E on page 103 . Measure the insulation resistance between
each phase conductor and the Protective Earth conductor using a measuring voltage
of 1000 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.
Attach the warning stickers in local languages
Connect the power cables
See figures C and F on pages 102 and 103 . Use symmetrical shielded cable for the
motor cabling.
1. Remove the front cover. IP21 units: Release the retaining clip with a screwdriver
(a) and lift the cover from the bottom outwards (b).
2. IP21 units: Remove the cable entry box cover by undoing the mounting screws.
3. Attach the residual voltage warning sticker in the local language next to the
control unit.
4. Remove the side plates of the cable entry box.
5. Remove the shroud on the power cable terminals by releasing the clips on the
sides with a screwdriver and lifting (a). Knock out holes for the cables (b).
6. For frames R8 and R9: If parallel cables are installed, knock out the shrouds on
the power cable terminals for the cables to be installed.
7. Cut adequate holes into the rubber grommets. Slide the grommets onto the
cables. Prepare the cable ends. Slide the cables through the holes of the bottom
plate and attach the grommets to the holes.
8. Ground the cable shields 360 degrees under the grounding clamps.
9. Connect the twisted cable shields to the grounding terminals.
10. Connect the conductors of the input and motor cables. Tighten the screws.
11. Units with D150: Connect the conductors of the brake resistor cable to the
R+ and R- terminals.
12. If parallel cables are installed, install the grounding shelf for them. Repeat steps 7
to 12.
13. Reinstall the shroud on the power terminals.
14. Reinstall the side plates of the cable entry box.
15. Secure the cables outside the unit mechanically.
