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 unit 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.
