Spectra T120 Robotics Assembly Replacement Instructions This document provides instructions on how to replace a robotic assembly ® in the Spectra T120 library. Illustrations Whenever possible, the illustrations in this guide show the components from the front of the library, either looking at the front of the library or in through the front door. When it is helpful, the E/E port— located in the front door—is referenced as a “landmark” of the component location. Model Variations The model you are installing may vary slightly from the illustrations in this document; however, the steps in the procedure are the same regardless of the replacement model. If your assembly includes a T8 Torx L‐key and screw, use them as noted. Time Estimate The procedure takes approximately 60 minutes. REPARE FOR AINTENANCE Ensure ESD Protection The repair environment for the library must be free of conditions that could cause electrostatic discharge (ESD). To protect the library from ESD, follow these procedures when repairing or testing the library: Place a static protection mat on the work surface used while removing and installing library components. Use a 1‐megohm resistor to ground the static protection mat. Wear a static protection wrist band or grounding foot strap whenever ...
