Power Wiring and Grounding—Frames 8…15
These diagrams show products connected to a solid ground single point (PE only) power source. Some applications may require alternate grounding schemes, see DRIVES-IN001 for more information. These applications include installations with long distances between drives or drive line-ups, which could cause large potential differences between the drive or line-up grounds.
For installations within a cabinet, a single safety ground point or ground bus bar connected directly to building steel should be used. All circuits including the AC input ground conductor should be grounded independently and directly to this point/bar.

In-line Configuration:
Back-to-Back Configuration:
Important: All required electrical connections between the entry wire bays are made at the factory. No additional connections are to be made at installation. Do not remove any factory-installed bus bar components that are designed to help prevent such connections. | (Entry wire bay is optional for frames 10…12.) Entry Wire Bay to Input Bay In-line Configuration:
Back-to-Back Configuration:
| Input Bay to Power Bay All Configurations:
Important: An electrical connection between the PE ground bus bars in these cabinets is not allowed. Do not remove the factory-installed bus bar components that are designed to help prevent such a connection. PE ground integrity is maintained between the input bay and power bay by the factory-installed hardware that is used to join the cabinets. | Power Bay to Power Bay All Configurations:

Typical Grounding—Frames 8...15
Item | Description |
|---|---|
A | Branch circuit devices and remote disconnect as required by local electrical codes. |
B | DC bus conditioners are connected to the PE ground bar with a single ground wire and clamp. The number of DC bus conditioners that are installed depends on input voltage class, any selected power option (-P50 or -P51), and the AC supply ground scheme. |
C | LCL filter module and power module PE ground connections are made via the chassis-to-support bracket connections. |
D | Motor lead connections |
E | Do Not Remove Factory installed bus bar components indicate make no electrical connections at these points. |
F | Grounding clamp connections |
