Rockwell Automation 1734-TBS_-TB3S_RTBS_RTB3S 1734-TB3 TB3S Installation Instructions - Manual (Page 2)

1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the
number required for the type of module being installed aligns with the notch in the base.
2. Make certain the DIN rail locking screw is in the horizontal position. (You cannot insert
the module if the locking mechanism is unlocked.)
3. Insert the module straight down into the mounting base and press to secure. The module
will lock into place.
Install the Removable Terminal Block (RTB)
A removable terminal block 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.
Remove a Mounting Base
To remove a mounting base, you must remove any installed module, and the module installed in
the base to the right. Remove the removable terminal block (if wired).
1. Unlatch the RTB handle on the I/O module.
2. Pull on the RTB handle to remove the removable terminal block.
3. Press on the module lock on the top of the module.
4. Pull on the I/O module to remove from the base.
5. Repeat steps 1, 2, 3 and 4 for the module to the right.
6. Use a small bladed screwdriver to rotate the orange base locking screw to a vertical
position. This releases the locking mechanism.
7. Then lift straight up to remove.

Install the Mounting Base
To install the mounting base on the DIN rail, proceed as follows.
1. Position the mounting base vertically above the installed units (adapter, power supply or
existing module.
2. Slide the mounting base down allowing the interlocking side pieces to engage the
adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail. The mounting base will snap into
place.
4. To remove the mounting base from the DIN rail, remove the module, and use a small
bladed screwdriver to rotate the base locking screw to a vertical position. This releases the
locking mechanism. Then lift straight up to remove.
Install the I/O Module
The module can be installed before, or after base installation. Make sure that the mounting base is
correctly keyed before installing the module into the mounting base. In addition, make sure the
mounting base locking screw is positioned horizontal referenced to the base.
