8. Attach a residual voltage warning sticker to the drive in the local language
Frames R1...R4: to the control panel mounting platform, Frames R5...R9: next to the control unit. See examples above.
9. 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) without any modifications to
the built-in EMC filter or varistors. If you install the drive to a different system, reconfigure the EMC and VAR screws as
shown in the table below. The table also shows the optional modifications available

1) Metal screw must not be used.
2) Optional, for better noise filtering.
3) Frames R4 and R5 are evaluated for use on corner-grounded delta networks or midpoint grounded delta systems by UL
standards. Do not use frames R4 and R5 on IEC installations with corner grounded networks.
4) R7 has no EMC (DC) screw for 600 V.
5) IEC drives manufactured outside North America have these screws installed by default.
10. 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 or 77 °F). 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.
