1.11 Conduit
All probe and sensor cabling to the SiteSentinel iTouch Controller must be in rigid steel conduit. The conduit
must be dedicated to intrinsically safe wiring for this Controller.
Probe and sensor wiring for this Controller can share the same conduit.
This Controller’s intrinsically safe wiring cannot share the same conduit with other equipment’s intrinsically safe
wiring.
NOTE: PVC conduit may be substituted for rigid steel conduit where acceptable by local codes. Use
SHIELDED cable for sensor and probe wiring as described in the above sections.
The size and number of probe and sensor conduits (probe-sensor-to-controller) depends on how many probes
and sensors your site has.
It is recommended to group probe wires into separate conduits for each SiteSentinel iTouch Controller I.S.
Interface Module position.
