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
.
Figure 1.3 Typical grounding
Safety Ground – (PE)
This is the safety ground for the drive that is required by code. One of these points must be connected
to adjacent building steel (girder, joist), a floor ground rod or bus bar. Grounding points must comply
with national and local industrial safety regulations and/or electrical codes.
Shield Termination – SHLD
Either of the safety ground terminals located on the power terminal block provides a grounding point
for the motor cable shield.
The motor cable shield connected to one of these terminals (drive end) should also be connected to
the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to the safety
ground terminal.
The conduit box option may be used with a cable clamp for a grounding point for the cable shield.
When shielded cable is used for control and signal wiring, the shield should be grounded at the source
end only, not at the drive end.
