Danger!
Explosion hazard from using of non-intrinsically safe circuits in intrinsically safe circuits
Using non-intrinsically safe devices in intrinsically safe circuits suspends the type of
protection. This can ignite the surrounding potentially explosive atmosphere.
Do not use HART multiplexer devices and HART termination boards in intrinsically safe
circuits.
Danger!
Explosion hazard from live wiring of circuits
If you connect or disconnect energized circuits in a potentially explosive atmosphere, sparks
can ignite the surrounding atmosphere.
Only connect or disconnect energized circuits in the absence of a potentially explosive
atmosphere.
