RKI Instruments 35-3000RKA-10 - Manual (Page 12)

12 • 35-3000RK-10 PPM Hexane Sample Draw Detector
CAUTION: If using shielded cable, leave the cable’s drain wire disconnected and
insulated at the sample draw detector. You will connect it to an available
chassis ground at the controller.
7. Route the shielded cable or wires in conduit leading from the sample draw detector to
the controller.
8. Connect the cable’s drain wire to an available chassis ground at the controller. A
ground stud is typically a convenient location to connect to chassis ground in an RKI
controller.
