Make the A Quad B connections at the bottom of the system module
(refer to Figure 5.3) as follows:
To improve the bond between the motor feedback cable shield and the
system module PE ground, a cable shield clamp is included with the
Series C system modules.
Ensure an appropriate amount of the cable insulation and braided
shield is removed from the feedback cable. Place the cable wires and
exposed braided shield into the cable shield clamp and tighten the
clamp screw. Then thread the bracket screw into the bottom of the
system module and tighten. Refer to the figure below for an
illustration.
