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.
