Using the cable clamp included in the delivery of the drive, ground the shield of
the PROFIBUS cable to the frame of the AC drive.
NOTE: This can be done in all drives if there is no difference in PE potential
between the drives. However, if there is PE potential difference then the shield
should be connected to PE only at one point in the system. The shields of the
cables shall be joint but not connected to several PE points with different potential.
