2.3 Installing the Removable Terminal Block
A removable terminal block is supplied with the mounting base assembly. To
remove, pull up on the RTB handle. This allows the base to be removed and
replaced as necessary without removing any of the wiring. Follow the following
instructions to reinsert the removable terminal block:
1. Insert the RTB end opposite the handle into the base unit. This end has a
curved section that engages with the mounting base.
Warning: When you connect or disconnect the Removable Terminal Block
(RTB) with the field side power applied, an electrical arc can occur. This could
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is non-hazardous before proceeding.
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.
