7. Make sure that the drive is compatible with the grounding system
You can connect all drives to a symmetrically grounded TN-S system (center-grounded wye). If you install the drive to a
different system, you may need to remove the EMC screw (disconnect the EMC filter) and/or remove the VAR screw
(disconnect the varistor circuit).

1) A residual current device must be installed in the supply system. In NEC installations the residual current device is only
required at or above 1000 amps.
2) ABB does not guarantee the EMC category or the operation of the ground leakage detector built inside the drive.
8. Measure the insulation resistance of the power cables and the motor
Measure the insulation resistance of the input cable before you connect it to the drive. Obey local regulations.
Measure the insulation resistance of the motor cable and motor when the
cable is disconnected from the drive. Measure the insulation resistance
between each phase conductor and the PE 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, see the manufacturer's instructions. Moisture
inside the motor decreases the insulation resistance. If you think that there
is moisture, dry the motor and do the measurement again.
