Determine the Input Power
Configuration
Before wiring input power to your DC-bus power supply, you must determine
the type of input power within your facility. The drive modules are 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.
