Remove Power

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.
