7. Attach a residual voltage warning sticker to the drive in the local language

8. 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 must remove the EMC screw (disconnect the EMC filter) and/or remove the VAR screw (disconnect

the varistor circuit).

Do not remove EMC or

VAR screw.

1) A residual current device must be installed in the supply system.

2) ABB does not guarantee the EMC category or the operation of the ground leakage detector built inside the drive.

9. Measure the insulation of the power cables and the motor

Measure the insulation of the input cable before you connect it to the drive. Obey

the local regulations.

Measure the insulation 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 [77 °F]). For the insulation resistance of other motors, see the

manufacturer's instructions. Moisture inside the motor casing decreases the

insulation resistance. If you think that there is moisture inside the motor casing, dry

the motor and do the measurement again.

10. Connect the power cables

CAUTION! ABB recommends to use a lightning pole to avoid lightning strike to the drive. Make sure that the

lightening pole ground is not common for PV cell, drive, and motor.
