PowerVault 130T Service Manual Preventing Electrostatic Discharge Damage Reinstall covers and close doors when equipment is not being serviced. If the grounding-kit work surface has been exposed to temperatures above 66°C (150°F) or below 4.5°C (40°F), acclimate the work surface to room temperature before unrolling it. Place any removed component into an ESD-protective package. Keep the grounding-kit work surface clean. Use a mild detergent and water, as needed, and make sure that the surface is completely dry before you use it. Periodically check the resistance of the ground cord and the wrist-strap coil cord. The ground cord should measure less than 1.2M ohms , and the coil cord should measure between 0.8M ohms and 1.2M ohms. Repair or replace the cords as required. ESD-Protection Procedure Remember that each environment is different. Make sure that all concerns have been addressed before working on equipment. Preparation 1.
