Unpack and Install the Module
Remove the packaging and inspect the module. Contact NI if the module is damaged. Do not
install a damaged module.
Caution The module is static sensitive. Always properly ground yourself and the
equipment when handling or connecting to the module.
Complete the following steps to install the NI PXIe-4300 while referring to Figures 1 and 2:
Note To maintain forced air cooling in the PXIe system, refer to the Maintain
Forced-Air Cooling Note to Users.
1. Plug in your chassis before installing the NI PXIe-4300. The power cord grounds the
chassis and protects it from electrical damage while you install the module.
2. Make sure the chassis is powered off.
Caution To protect yourself, the chassis, and the NI PXIe-4300 from electrical
hazards, leave the chassis powered off until you finish installing the NI PXIe-4300
module.
3. Touch a metal part on the chassis to discharge any accumulated static electricity.
4. Identify a supported PXI Express slot in the chassis. NI PXIe-4300 modules can be placed
only in PXI Express Peripheral slots, PXI Express Hybrid Peripheral slots, and PXI Express
System Timing slots. Refer to the chassis documentation for details.
Figure 1. Symbols for PXI Express/PXI Express Hybrid/PXI Slots
5. Remove the filler panel, and touch any metal part of the chassis to discharge static
electricity.
6. Place the module edges into the module guides at the top and bottom of the slot.
Caution When installing the module, make sure both edges are positioned inside
the guides and that the module components do not come into contact with adjacent
modules.
7. Slide the module along the guides until it reaches the rear connector, then seat the module
by pushing the front panel until it is flush with the front panel of the chassis.

Connect the Signals
Note Refer to the Read Me First: Safety and Electromagnetic Compatibility before
removing equipment covers or connecting or disconnecting any signal wires.
To connect signals to the terminal block, refer to Figures 3 and 4 while completing the following
steps:
Note You can find the pinout names and locations in MAX at any time by
right-clicking the device name under Devices and Interfaces and selecting
Device Pinouts.
1. Loosen the captive top cover screws and remove the top cover.
2. Loosen the strain-relief screws and remove the strain-relief bar.
3. Prepare the signal wire by stripping the insulation no more than 7 mm (0.28 in.).
4. Run the signal wires through the strain-relief opening.

5. Insert the stripped end of the signal wires fully into the appropriate terminal. Refer to the
label next to each screw terminal to determine the function of the terminal. The
NI PXIe-4300 User Manual provides more detailed wiring information. Make sure no
exposed wire extends past the screw terminal. Exposed wire increases the risk of a short
circuit that can cause circuit failure.
Note For accurate measurements, the COM terminal for the channel being used
must be connected to the ground of the AI source being measured. For the TB-4300C,
connect AI- to COM for the channel being used.
