INSTALLATION GUIDE
TBX-96 T
ERMINAL
This guide describes how to install and use the TBX-96 terminal block with
the SCXI-1100, SCXI-1102B/C, SCXI-1104/C, and SCXI-1581 modules.
The TBX-96 is a shielded, DIN-rail mountable terminal block with
96 screw terminals for easy connection to the SCXI-1100, SCXI-1102B/C,
SCXI-1104/C, and SCXI-1581 front connector. The TBX-96 mounts on
most European standard DIN EN mounting rails.

Safety Information
Cautions
may be flammable gases or fumes.
Do not operate damaged equipment. The safety protection features built into this terminal
block can become impaired if the device becomes damaged in any way. If the terminal
block is damaged, turn the terminal block off and do not use it until service-trained
personnel can check its safety. If necessary, return the terminal block to National
Instruments for service and repair to ensure that its safety is not compromised.
Do not operate this equipment in a manner that contradicts the information specified in this
document. Misuse of this equipment could result in a shock hazard.
Do not operate the terminal block in an explosive atmosphere or where there
Do not substitute parts or modify equipment. Because of the danger of introducing
additional hazards, do not install unauthorized parts or modify the device. Return the
device to National Instruments for service and repair to ensure that its safety features are
not compromised.
Yo u must insulate all of your signal connections to the highest voltage with which the
TBX-96 can come in contact.

Connections, including power signals to ground and vice versa, that exceed any of the
maximum signal ratings on the TBX terminal block can create a shock or fire hazard, or
can damage any or all of the boards connected to the SCXI chassis, the host computer, and
the TBX terminal block. National Instruments is not liable for any injuries or damage
resulting from incorrect signal connections.
Clean the TBX-96 by brushing off light dust with a soft non-metallic brush. Remove other
contaminants with a stiff non-metallic brush. The unit must be completely dry and free
from contaminants before returning it to service.
Connecting the Signals
Note
connecting or disconnecting any signal wires.
Refer to the Safety Information section before removing equipment covers or
Figure 1 shows the layout of the TBX-96 terminal block circuit board.
To connect a signal to the terminal block, perform the following steps while
referring to Figure 1:
1. Prepare your signal wire by stripping the insulation no more
than 7 mm.
2. Connect the signal wires to the screw terminals by inserting the
stripped end of the wire fully into the terminals. Refer to your SCXI
module user manual for examples of how to connect to field signals
and loads.
3. Tighten the terminals to a torque of 5-7 in.-lb (56-79 N-cm).
The signal connection is now complete.

Installing the Cable and Terminal Block
Perform the following steps to mount the SH96-96 or R96-96 cable
assembly and to connect the TBX-96 to your SCXI module. Refer to
Figures 2 through 4 as needed.
1. Turn off your SCXI chassis.
2. Turn off the computer that contains your data acquisition (DAQ)
device or disconnect the DAQ device from your SCXI chassis.
3. Connect the TBX cable adapter to the appropriate SCXI module and
secure it by tightening both thumb screws.
4. If you are using an SH96-96, verify that the two backshell mounting
ears on each end of the cable assembly are in the position shown in
Figure 2 and 3. If the backshell mounting ears are not in the position
shown, remove the backshell mounting ears and install them in the
position shown. If you are using an R96-96, the mounting screws are
built into the backshell.
