# Rails and Isolator

### Removing or replacing the rails and isolator

Alta X Gen2 comes with 12mm rails and the Smart Dovetail isolator. To remove them:

1. Place Alta X Gen2 upside down on a clean, flat surface.

2. Unplug the Smart Dovetail from Alta X Gen2’s IO panel. Grip the connector and depress the locking tab then gently unseat.

4. Slide the isolator off of the rails or open the levers and rotate the isolator to remove it from the rails.
5. Loosen the red rail tube levers then slide out the rails.
6. Using a 2.5mm hex driver, remove the four M3x10 combo head screws attaching the rails to the bottom of Alta X Gen2.

**To reinstall the rails and/or isolator:**

1. Place Alta X Gen2 upside down on a clean, flat surface.

2. Attach the two rail adapters to the bottom chassis with 4x M3x10 combo head screws. Only loosely tighten these.
3. Open the locking levers on the adapters and slide in the two 12x500mm tubes. Sliding in the tubes will align the adapters to be parallel.
4. Tighten the four screws fully, then close the locking levers to clamp the tubes.

5. Slide on or set the isolator on the rails. Close the locking levers loosely to retain the isolator on the rail.

6. If you are using the default payload offset for Alta X Gen2, position the isolator with 110mm between the isolator and rail adapter clamps.
   1. This ensures the best accuracy when mapping. If you have adjusted this for your application, mount the isolator accordingly.

7. When fully aligned, clamp the isolator fully onto the rails.

8. Plug in the Smart Dovetail cable into the Payload connector on the IO panel.
