1398-DDM-030 Product Description
Before you ground or wire your 1394 system you must determine the type of 360/480V input power you will be connecting to. The 1394 system is designed to operate in both grounded and ungrounded environments.
As shown in the figure below, the grounded power configuration allows you to ground your 3-phase power at a neutral point. Each 1394 system module has a factory-installed jumper configured for grounded power distribution. If you determine that you have grounded power distribution in your plant you do not need to modify your system.
