Install the Removable Terminal Block
A Removable Terminal Block (RTB) is supplied with your wiring base assembly. To
remove, pull up on the RTB handle. This allows the mounting base to be removed and
replaced as necessary without removing any of the wiring. To reinsert the Removable
Terminal Block, proceed as follows:
1. Insert the end opposite the handle into the base unit. This end has a curved
section that engages with the wiring base.
2. Rotate the terminal block into the wiring 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 electrical arc can occur. This could cause
an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
WARNING: When used in a Class I, Division 2, hazardous location, this
equipment must be mounted in a suitable enclosure with proper wiring method
that complies with the governing electrical codes.
