Connecting the Y-Series Cable Shield at the Motor
Y-Series motors have a short pigtail cable which connects to the
motor, but is not shielded. The preferred method for grounding the
Y-Series motor power cable on the motor side is to expose a section
of the cable shield and clamp it directly to the machine frame. The
motor power cable also has a 150 mm (6.0 in.) shield termination wire
with a ring lug that connects to the closest earth ground. Use this
method in addition to the cable clamp. The termination wire may be
extended to the full length of the motor pigtail if necessary, but it is
best to connect the supplied wire directly to ground without
lengthening. Refer to Figure 3.13 for an illustration and Figure B.15 in
Appendix B for the interconnect diagram.
