Determine the Input Power
Configuration

Before wiring input power to your Kinetix 7000 drive system you must determine
the type of input power to which you are connecting. The Kinetix 7000 drive is
configured at the factory to operate in a grounded power environment.

Grounded Power Configurations

Grounded (WYE) power wiring lets you ground your three-phase power at a
neutral point.

ATTENTION: When using a LIM with your Kinetix 7000 drive, the AC line input
power must come from a grounded configuration.

When not using a LIM with your Kinetix 7000 drive, ungrounded configurations are
acceptable, but you must set the jumper to prevent high electrostatic build-up.

See Setting the Ground Jumper in Ungrounded Power Configurations on

page 78
