Connecting the Kinetix 2000 Drive System 63
Determining Your Type of
Input Power Before wiring input power to your Kinetix 2000 system, you must determine
the type of input power you are connecting to. The IAM is designed to operate
in both grounded and ungrounded environments.
The following three-phase power distribution configurations are supported by
your Kinetix 2000 system.
Grounded Three-phase Power Configurations
The grounded (WYE) power configuration lets you ground your three-phase
power at a neutral point. This type of grounded power configuration is
preferred.
ATTENTION
When using a LIM with your Kinetix 2000 drive, the ac input power to
the VAC LINE terminal must come from a grounded configuration. This
is shown in the Grounded Three-phase Power Configuration (WYE
secondary) diagram on page 64.
When not using a LIM with your Kinetix 2000 drive, ungrounded
configurations are permitted, but you must set the jumper to prevent
high electrostatic build-up.
Refer to Setting the Ground Jumper in Ungrounded Power
Configurations on page 69 for more information.
