Determine the Input Power
Configuration
Before wiring input power to your Kinetix 6000 system, you must determine the
type of input power you are connecting to. The IAM module 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 37 - Grounded Power Configuration (WYE Secondary)
Refer to Power Wiring Examples beginning on page 201 for input power
interconnect diagrams with and without the LIM module.
ATTENTION: When using a LIM module with your IAM module, the VAC
LINE input power must come from a grounded configuration (refer to the
figure below).
When not using a LIM module with your IAM module, 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 83
