4.2 Grounding (Fig. 11 and Table 3)
Be sure to connect the ground line (labeled "G") to ground. Prior to grounding, ensure that the
wire is the proper one (labeled "G").
Also, verify that grounding continuity has been established inside the motor by checking that
ground wire (labeled "G") is electrically conductive with the bolt on the top of the motor (to be
stripped of paint to bare metal surface).
Ground the motor according to local codes.
