Caution This icon denotes a caution, which advises you of precautions to take to
avoid injury, data loss, or a system crash. When this symbol is marked on a product,
refer to the Safety Guidelines section for information about precautions to take.

Safety Guidelines
The following cautions contain important safety information concerning hazardous voltages
and connector blocks.
Caution Do not connect hazardous voltages (>30 V RMS/42 V peak/60 V DC).
Refer to your product documentation for information about the electrical limits of
your device or module.
Caution Install cover prior to use. To avoid electrical shock, do not remove
SCB-100A covers unless you are qualified to do so. Before removing the cover,
disconnect any live circuit from the connector block. Replace cover for use.
Caution The chassis ground lug on your SCB-100A is for grounding
high-impedance sources, such as a floating source (1 mA maximum) and for
terminating the shields of connected cables. Do not use the chassis ground lug as a
safety earth ground.
Electromagnetic Compatibility Guidelines

Caution The chassis ground lug on your SCB-100A is for grounding
high-impedance sources, such as a floating source (1 mA maximum) and for
terminating the shields of connected cables. Do not use the chassis ground lug as a
safety earth ground.
To get started with the SCB-100A, complete the following steps while referring to the
previous figures. If you have not already installed your DAQ device or module, refer to the
4| ni.com | SCB-100A User Guide

getting started guide that came with your product for instructions. Remove all cables from the
SCB-100A before getting started.
1. (Optional) Mount the SCB-100A to a panel or DIN rail, as described in the Mounting the
SCB-100A section.
2. Remove the cover.
3. Remove the film from both sides of the cover.
4. (Optional) Attach the quick reference label to the inside of the cover. For quick reference
labels for most compatible products, go to ni.com/info and enter the Info Code
scb100alabels.
Tip You can stand the cover in the SCB-100A for easy reference.
5. Loosen the strain-relief bar by removing the strain-relief screws with a #2 Phillips
screwdriver.
6. Connect the wires to the screw terminals by stripping off the wire insulation, inserting the
wires into the screw terminals, and securely tightening the screws with the flathead
screwdriver. Refer to the Specifications section for screw-terminal wiring gauge and
torque information.
Caution To ensure the specified EMC performance, signal wires routed
outside of the enclosure must be contained within a shielded cable and
connected to shielded accessories. Cable shields must be terminated to the
chassis ground lug using as short a connection as is practical.
7. Reinstall the strain-relief (if removed) and tighten the strain-relief screws. If the shielded
cable is too large to route through the strain-relief hardware, either use multiple,
smaller-diameter cables or remove the top strain-relief bar and add insulation or padding
if necessary to constrain the cable.
8. Replace the cover.
Caution You must install cover prior to use.
Caution Do not connect input voltages >30 V RMS/42 V peak/60 V DC to
the SCB-100A. Input voltages >30 V RMS/42 V peak/60 V DC can damage the
SCB-100A, all devices or modules connected to it, and the host computer.
9. Connect the SCB-100A to the DAQ device or module using the SH100-100-F cable.
Refer to the Specifications section for information about the SCB-100A I/O connector.
Note To ensure the specified EMC performance, operate this product only
with shielded cables.
10. Launch Measurement & Automation Explorer (MAX). In the left panel, expand Devices
and Interfaces to confirm that your DAQ device or module is recognized, and then
configure your device settings.
SCB-100A User Guide | © National Instruments | 5

11. (Optional) Configure the DAQ device or module connected to the SCB-100A by
completing the following steps.
a. In MAX, right-click your DAQ device or module and select Configure.
b. Configure the device or module properties and click OK.
12. Test specific device functionality. Run a Test Panel in MAX by right-clicking your DAQ
device or module and selecting Test Panels. Click Start to test the device or module
functions.
Note When you have finished using the SCB-100A, power off any external signals
connected to the SCB-100A before you power off your computer.
Mounting the SCB-100A
You can use the SCB-100A on a desktop, or mount it to a panel or a standard DIN rail. For
two-dimensional drawings and three-dimensional models of the SCB-100A, visit ni.com/
dimensions and search by product name.
Panel Mounting
Three keyholes are located on the back of the SCB-100A for mounting it to a panel or wall. To
mount the SCB-100A to a board or panel, complete the following steps.
1. Download and print the panel mounting template PDF by going to ni.com/info and
entering the Info Code scb100amounting.
2. Using the template, mark the three points on the panel. Verify that the narrow ends of the
panel mounting screw keyholes are pointing up.
3. Screw #6-32 panhead machine screws or M3 panhead machine screws into the points
marked on the panel, leaving room to easily remove the SCB-100A from the panel.
Installed screw height for both screw types (from the wall to the top of the screw) is
5 mm (0.2 in.).
DIN Rail Mounting
The NI 9913 DIN rail mounting kit (part number 781740-01) contains one clip for mounting
the SCB-100A on a standard 35 mm DIN rail. Fasten the DIN rail clip to the accessory using
two FLH #6-32 x 5/16" screws (included in the kit) with a #2 Phillips screwdriver, as shown in
the following figure.
Note The threaded holes on the SCB-100A for DIN rail mounting should not be
used more than five times. Unscrewing and reinstalling the DIN rail clip will
produce a compromised connection between the DIN rail clip and accessory.

Securing the Cover on the SCB-100A
In most cases, attaching the cover with the integrated magnets is sufficient. To permanently
secure the cover to the SCB-100A base, you will need two M3 × 6 (#4-40 × 5/16")
thread-forming Phillips panhead screws, such as Taptite® Trilobular® screws. You can
purchase Taptite screws from many vendors.
SCB-100A User Guide | © National Instruments | 7

Complete the following steps.
1. Using a 3.5 mm (9/64 in.) diameter drill bit, drill two holes through the silkscreened
crosshairs on the label side of the cover. When drilling, place the cover on a flat surface,
such as a drill press, and drill slowly to minimize burrs.
2. Replace the cover on the base, lining up the drill holes with the holes in the enclosure.
3. Screw the M3 × 6 (#4-40 × 5/16") screws in with a torque of 0.90 N · M to 1.13 N · M
(8 in. · lb to 10 in. · lb). Screwing within the recommended torque range avoids stripping
the threads of the enclosure holes.
Removing the SCB-100A PCB from the Base
Complete the following steps to remove the SCB-100A from the base.
1. Disconnect the cable from the SCB-100A, if connected, and remove the top cover.
2. Loosen the strain-relief screws, shown in Figure 1, with a #2 Phillips screwdriver.
3. Remove any signal wires from screw terminals with a flathead screwdriver.
4. Remove the printed circuit board mount screws and chassis ground lug, shown in
Figure 2, with a #1 Phillips screwdriver.
5. Remove the connector screws, shown in the following figure, with a flathead screwdriver.
6. Tilt the PCB up and pull it out of the enclosure base.
