Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 9)

Installation/Wiring 2-3
• The power source has frequent interruptions.
If these conditions exist, it is recommended that the user install a minimum amount of
impedance between the drive and the source. This impedance could come from the
supply transformer itself, the cable between the transformer and drive or an additional
transformer or reactor.
2.2 General Grounding Requirements
The drive Safety Ground - PE 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.
Refer to Figure 2.2 and Table 2.1.
