CAUTION—All eld wiring must conform to the National Electrical Code, NFPA 70,
Article 501-4(b) for installations within the United States or the Canadian Electric
Code for installations within Canada. Local wiring ordinances may also apply. All
eld wiring must have a wire range of 22 to 14 AWG and terminal block screws must
be tightened to a minimum torque of 5 to 7 in-lb to secure the wiring within the ter-
minal block. Only personnel who are experienced with eld wiring should perform
these procedures.

Note—An RS-485 converter is required to connect a computer to the
MC-III ow analyzer. The instructions below are for an RS-485-to USB
converter (Part No. 2296650-01). An RS-485-to-RS-232 9-pin converter
(Part No. 9A-101283116) is also available.
