The PDUs achieve earth ground through their power cords. For additional grounding, optionally attach a chassis earth ground cable to the rack. The additional ground point enables electrical current leakage to dissipate more efficiently.
Caution - Do not install a ground cable until you confirm that there is proper facility AC receptacle grounding. The PDU power cords and the ground cable must reference a common earth ground. |
An earth ground is required. See Grounding Requirements. Consult with your facilities manager or a qualified electrician for the specific instructions at your data center.
The ground cable attachment area might have a painted or coated surface that must be removed to ensure solid contact.
