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 end opposite the handle into the base unit. This end has a
curved section that engages the wiring base.
2.
Rotate the RTB 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.
Removing a Wiring Base
In order to remove a wiring base, you must remove any module installed
in the base, and any installed module to the right of the base, and remove
the removable terminal block (if wired).
1.
Snap open the RTB removal handle, or remove the removable terminal
block.
2.
Squeeze the module locking mechanism and pull up to remove the
module(s).
3.
Turn the wiring base locking screw to a vertical position to unlock the
base from the DIN rail.
4.
Slide the wiring base up to release it from its mating units.
Refer to the user manual for keying information, specifications and how to
configure your module.
