ATTENTION: Remove power before making or breaking cable
connections. 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.
