Integral to a completed low voltage or medium voltage controller
The SyncPro II is also available as a component of a Rockwell Automation/Allen-
Bradley synchronous motor controller, incorporating the components shown in
. Although the layout in the starter is different, control and functionality
remain the same.
Grounding
The grounding required by the SyncPro II panel has been brought to a common
grounding bar mounted on the panel. It is important that once the unit is installed,
that this grounding bar is wired to the starter ground bus. It is important that a proper
ground is made as the SyncPro II has a number of low voltage signals which, if not
properly grounded, may be vulnerable to noise causing erratic operation.
