The CD20 mounts directly to the C-Series sample probe via the DC-2 coupling. The DC-2 coupling should be hand-tightened to ensure that the internal retaining ring is not pushed out of its groove. If the DC-2 coupling is over-tightened at the CD20 hub, the motor shaft will not engage the DC-1 coupling on the probe. - Page 6 Figure 1—Field wiring of CD20 (230VAC) assembly Figure 2—CD20 (230VAC) control card (full view) April 2004...
