For EMC purposes, under no circumstances should you leave cable
shields disconnected at one end or both ends of the cable (analyzer or
control unit or other device).
Shield Ring Method
Connect all shields for that conduit entry (other than power) to a supplied
shield terminal ring (see Figure 25). This shield ring is a stainless steel ring
with a metal tab. Place the shield ring under the conduit nut. Crimp the
shields from all cables for that conduit entry to a 1/4-inch female quick
disconnect, then push it onto the tab that sticks out of the conduit shield
ring. Keep shields as short as possible.
Ground Stud Method
Connect all cable shields for that conduit entry to the grounding stud clos-
est to that conduit entry hole.
