Gemini GV Hardware Installation Guide
System Installation
If you mount the Gemini drive in an enclosure, terminate cable braids (screens) at
the entrance of the enclosure. However, the motor braid must be returned to the
drive’s saddle clamp (GV-H20n/H40n: R-Clamp on front of drive), not any other
location.
The next figures show typical EMC installations.
