Adding, Removing and
Replacing Components About Removal and Insertion Under Power
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.
You can remove and insert the FIM without removing power. The
removal of the FIM results in the loss of communications with both H1
fieldbus links.
The removal of an individual fieldbus device only breaks
communications with that device.
WARNING
!
When you insert or remove the module while
backplane power is on, an electrical arc can occur.
This could cause an explosion in hazardous location
installations. Be sure that power is removed or the
area is nonhazardous before proceeding.
IMPORTANT
This is a general document on how to use
ProcessLogix tools and that full maintenance should
use live analysts. This document is not intended to
