ATTENTION
!
Remove power before removing or inserting this
module. When you remove or insert a module 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.
