Figure 1-12: CSA Non-Incendive Field Wiring Installation
A. Metal conduit
B. Recommended sensor attached. See Drawing 1700704 for sensors
recommended for use with option -31. (No sensor if blank or -38).
C.
Use with non-flammable process media only.
D. Rosemount Clarity II turbidity sensor (to option -37), pH sensor (to option
-32), amperometric sensor (to option -34, -35, or -36), contacting
conductivity sensor (to option -30), or any simple apparatus to the same
connections. No sensor if option is blank or -38.
E. Rosemount Clarity II turbidity sensor (to option -27), pH sensor (to option
-22), amperometric sensor (to option -24, 25, or -26), contacting
conductivity sensor (to option -30), or any simple apparatus to the same
connections.
F. Sensor 1. See Drawing 1700704 for sensors recommended for use with
option -21.
G. Unclassified area
H. Sensor cable is shielded.
I. During installation, leave maximum amount of jacket insulation possible
on N.I. field wiring within instrument enclosure. After termination, wrap
N.I. field wiring within enclosure with mylar tape to ensure adequate
double insulation remains.
Max. cable length is 50 ft. (15.2 m).
You may use non-incendive field wiring methods to connect sensor to the
turbidity, amperometric, pH, and contacting conductivity sensor boards.
Attached pH, contacting conductivity, or amperometric sensor boards
must be CSA approved as non-incendive for Class I, Division 2, Groups
ABCD with entity input values of Vmax and Imax ≥ Voc and Isc listed in
