Installing or Removing the Module Under Power
You can install or remove the module while chassis power is applied
if you observe the following precautions.
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
actuators 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.
