TBX-96 Terminal Block
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
Refer to the
Safety Information
section before removing equipment covers or
connecting or disconnecting any signal wires.
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.
