See table below for a summary of power terminal wiring specications.
z NOTE: Wire type not specied by the manufacturer. Some types of wire may not t within the
constraints of the conduit entry and bend radius inside the drive.
4.1.4 Grounding and Ground wire sizes
The drive contains high power and high frequency switching devices, leakage current may ow
between the drive and ground. Ground the drive to avoid electrical shock.
Connect only to the dedicated ground terminal of the drive. Don’t use the case or chassis screw for
grounding.
If multiple drives are installed near each other, each must be connected to ground directly. Take care
not to form a ground loop between the drives and the grounding location.
The protective earth conductor must be the rst one in being connected and the last one in being
disconnected.
The grounding wire conductor size shall comply with all local regulations. The ground wire shall be as
short as possible and should be connected to a ground point as near as possible to the drive.
