When you remove or insert a cable connector with power applied, an electrical
arc may occur. An electrical arc can cause personal injury or property damage by:
•
sending an erroneous signal to your system’s field devices, causing unintended
machine motion

causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the module and its
mating connector. Worn contacts may create electrical resistance.
