Grounding the Drive 4-1

CHAPTER 4

Grounding the Drive

The drive Safety Ground - must be connected to system

ground. Ground impedance must conform to the requirements of

national and local industrial safety regulations and/or electrical

codes. The integrity of all ground connections should be periodically

checked.

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.

ATTENTION: The following information is merely a

guide for proper installation. Rockwell Automation

cannot assume responsibility for the compliance or

the noncompliance to any code, national, local or

otherwise for the proper installation of this drive or

associated equipment. A hazard of personal injury

and/or equipment damage exists if codes are

ignored during installation.
