WARNING
!
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.
