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 and can lead to premature
failure.
