4.1Grounding the Drive

ATTENTION:The following information is merely a guide for proper installation. Baldor Electric Company 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.

ATTENTION:Use the dedicated ground terminal to ground the drive. Do not use the screw in the case or chassis, etc for grounding.

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.

Ground Fault Monitoring

If a system ground fault monitor is to be used, only Type B devices should be used to avoid nuisance tripping.

Safety Ground -

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.

Motor Ground

The motor ground must be connected to one of the ground terminals on the drive.
