ABB ACH580-04 Kurzanleitung Für Die Installation Seite 5

See figure F on page 97:
•
Attach the drive module to the pedestal guide plate.
•
Attach the drive module from its top to the punched section at the cabinet back. Note:
The fastening bracket grounds the drive module to the cabinet frame.
Measure the insulation of the input and motor cables and
the motor
Before you connect the input power cable to the drive, measure its insulation according to
local regulations.
See figure H on page 98. Ground the motor cable shield at the motor end. For minimal
interference, make a 360-degree grounding at the cable entry, or keep the pig tail short.
Measure the insulation of the motor and motor cable when the motor cable is
disconnected from the drive, see figure
between each phase conductor and the Protective Earth conductor. Use a measuring
voltage of 1000 V DC. The insulation resistance of an ABB motor must be more than
100 Mohm (reference value at 25 °C). For the insulation resistance of other motors, refer
to the manufacturer's instructions. Note: Moisture inside the motor casing reduces the
insulation resistance. If you suspect moisture, dry the motor and repeat the measurement.
Check the grounding system compatibility
EMC filter compatibility

The drive has an internal EMC filter (+E210) as standard. You can install the drive with the
EMC filter connected to a symmetrically grounded TN-S system, IT system, corner-
grounded delta, mid-point-grounded delta and TT system.
Ground-to-phase varistor compatibility

The drive is equipped with an internal ground-to-phase varistor as standard. You can
install the drive with the ground-to-phase varistor connected to a symmetrically grounded
TN-S system, corner-grounded delta and mid-point-grounded delta system. If you install
the drive to an IT system or a TT system, you need to disconnect the varistor. See section
Ground-to-phase varistor disconnecting instructions – IEC, not North America in the
hardware manual.
WARNING! Do not install the drive with ground-to-phase varistor connected to a
system that the varistor is not suitable for. If you do, the varistor circuit can be
damaged.
Connect the power cables (and install the shrouds for
option +B051)
See figure G on page 98.
Step
1 Install the grounding terminal to the drive module base.
2 Run the motor cables to the cabinet. Ground the cable shields 360 degrees at
the cabinet entry.
3 Connect the twisted shields of the motor cables to the grounding terminal.
