2. Pull on the RTB handle to remove the removable terminal block.
3. Press on the module lock on the top of 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 you insert or remove the module while
backplane power is on, or 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 power is removed or the
area is nonhazardous before proceeding.
