Install the Module Chapter 4
Follow these directions to reinsert the RTB.
1. Insert the RTB end opposite the handle into the base unit, noting that this
end has a curved section that engages with the mounting base.
2. Rotate the terminal block into the mounting base until it locks itself in
place.
3. If an I/O module is installed, snap the RTB handle into place on the
module.
Remove a Mounting Base
To remove a mounting base, you must remove any installed module and the
module installed in the base to the right. If the mounting base has a removable
terminal base (RTB), unlatch the RTB handle on the I/O module and pull on the
handle to remove the RTB.
1. Pull up on the I/O module to remove it from the base.
2. 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.
3. Use a screwdriver to rotate the orange DIN-rail locking screw on the
mounting base to a vertical position, noting this releases the locking
mechanism.
4. Lift the mounting base off the DIN rail.
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.
