Intrinsically Safe Wiring Diagram
The following diagram illustrates a Quantum Intrinsically Safe module using a
separate raceway to isolate its external wiring to the hazardous area. This is just one
of the possible ways of field wiring the module. Other methods would include
bundling and laying the intrinsically safe wires in the same wiring trough with the
bundled non-intrinsically safe wires, with each bundle tied down and separated by
minimum of two inches of air space through out the wiring runs.
