Determine the Input Power
Configuration
Before wiring input power to your Kinetix 7000 drive system, you must
determine the type of input power within your facility. The drive is designed to
operate in both grounded and ungrounded environments.
Grounded 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.
Figure 44 - Grounded Three-phase Power Configuration - (WYE Secondary)
ATTENTION: When you are using a LIM module with your Kinetix 7000 drive,
the AC line input power must come from a grounded power configuration.
When you are not using a LIM module with your Kinetix 7000 drive, ungrounded,
corner-grounded, and impedance-grounded input power configurations are
permitted, but you must set the ground jumper as indicated in Table 33
. In
addition, set the ground jumper when an active converter supplies the DC-bus
voltage.
See Set the Ground Jumper in Select Power Configurations
on page 77 for
additional information.
If you determine that you have grounded power distribution in your facility,
you do not need to set the ground jumper.
