Chapter 4 Install the Module
Connect the Removable Terminal Block
If a removable terminal block (RTB) is supplied with your mounting base
assembly, you must remove it by pulling up on the RTB handle. This action lets
you remove and replace the base as necessary without removing any of the wiring.
To reinsert the RTB, follow these directions.
1. Insert the RTB end opposite the handle into the base unit, note 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.
WARNING: When you connect or disconnect the removable terminal block
(RTB) with field-side power applied, an electric arc can occur. This arc could
cause an explosion in hazardous location installations. Be sure that power is
removed or the area is nonhazardous before proceeding.
