WARNING
These modules are designed so you can remove and insert them under
power. However, take special care when removing or inserting modules in an
active process. I/O attached to any module being removed or inserted can
change states due to its input/output signal changing conditions.
If you insert or remove the terminal base 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.
