1-4 Installing the ASCII Module
Installing the Removable
Terminal Block A removable terminal block is supplied with your 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. To reinsert the removable terminal block, 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 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.
Hook the RTB end into
the mounting base end,
and rotate until it locks
into place.
