Install the Removable
Terminal Block
A removable terminal block (RTB) is supplied with your mounting base
assembly.
To remove, pull up on the RTB handle. This lets you remove and replace the
base when necessary without removing any of the wiring.
To re-insert the RTB, proceed as follows.
1. Insert the RTB end opposite the handle into the base unit.
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 RTB with field-side power
applied, 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.
