3. Press in on the module lock on the top of the module, and pull up on the
I/O module to remove it from the base.
4. Remove the module to the right of the base you are removing, noting that
the interlocking portion of the base sits under the adjacent module.
5. Use a small-bladed screwdriver to rotate the orange DIN-rail locking screw
on the mounting base to a vertical position, noting that this releases the
locking mechanism.
6. Lift the mounting base straight up to remove.
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 to remove power or that the
area is nonhazardous before proceeding.
