applied.
WARNING
Publication
1756-IN019C-EN-P - November 2004
When you insert or remove a module while
backplane power is on, 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
device causing unintended machine motion or loss
of process control
• causing an explosion in a hazardous environment
Repeated electrical arcing causes excessive wear
to contacts on both the module and its mating
connector. Worn contacts may create electrical
resistance that can affect module operation.
