Caution Do not touch the contacts or remove the I/O boards or cables while the system is energized.

NI recommends loosely installing all RTIs before installing modules. Complete the following steps to install the RTI-12301

  1. Power off the main DC power source or disconnect it from the chassis before installing any RTIs.
  2. Ensure that the chassis is powered off.
    The POWER LED should be off. If it is not off, do not process until it is off.
  3. Loosen the screws of the upper rear panel.
  4. Position the RTI-12301 at the desired slot and insert the securing screws, but do not fully tighten them.
  5. Insert a module into the same slot as its corresponding RTI-12301 while firmly holding the RTI-12301 in place until the RTI-12301 is firmly connected to the module.
  6. Repeat steps 4 and 5 for all required RTIs.
  7. Tighten the screws for all RTI-12301s and the upper rear panel.
    This ensures proper alignment for future connections between modules and RTIs.
  8. Tighten the two module mounting screws on each newly installed module.
