Emerson Unidrive M201 Installation Manual page 79

Figure 4-17 and Figure 4-18 illustrate the preferred construction of cable and the method of
clamping. The outer sheath of the cable should be stripped back enough to allow the clamp to be
installed. The shield must not be broken or opened at this point. The clamps should be installed close
to the drive or feedback device, with the ground connections made to a ground plate or similar
metallic ground surface.

To ensure suppression of radio frequency emission, observe the following:
• Use a cable with an overall shield
• Clamp the overall shield to grounded metallic surfaces at both the
encoder and the drive, as illustrated in section 4-18
