Install the Removable Terminal Block
Read this for information if a removable terminal block (RTB) is
supplied with your wiring base assembly, noting that 1734-TOP and
1734-TOPS bases do not have an RTB.
To insert the RTB, proceed as follows. Note that if you pull up on the
RTB handle to remove the RTB, you can remove and replace the
mounting base as necessary without removing any of the wiring.
1. Insert the end opposite the handle into the base unit, noting
that 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 into place.
3. If an I/O module is installed, snap the RTB handle into place
on the module.
Wire the Module
See the figure and tables for information about how to wire 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
If you connect or disconnect wiring while the field-side power is
on, 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.
