Generally instrument cabling is usually run in. Few factors are to be considered or taken care of while wiring a field instrument to control panel. Based on noise susceptibility limits (NSL) according to IEEE 815 standard, various field instrument signals are classified as below. Noise Susceptibility Limit Grounding of the signal cable Type of cable Cable Terminations Based on noise susceptibility limits (NSL). Note how the hoop-shaped “jumper” wires are all cut to (nearly) the same length, and how each of the wire labels is oriented such that the printing is easy to read: This next photograph shows a great way to terminate multi-conductor signal cable to terminal blocks. Each of the pairs was twisted. A well-designed and properly installed instrument junction box is crucial for the efficient operation and maintenance of electrical systems. Level 1: High to medium susceptibility Level 2: Low susceptibility.
