This technical report includes requirements for a centralized powering approach that can be used to support distributed powered nodes such as those utilized in 5G cellular network deployment. This centralized powering solution leverages a single connection to an energy source such as renewables or the commercial power grid to deliver power to multiple remotely located elements that can be installed thousands of feet away from the centralized power source with a previously unattainable combination of safety and transmission efficiency. These Fault Managed Power Systems (FMPSs) employ sophisticated monitoring and controls, including an electronic handshake to verify that the powered device (PD) is present and operating correctly before greater than Class 2 power is applied to the circuit. This TR establishes a human contact fault analysis methodology to determine whether a risk of ventricular fibrillation exists in powering systems evaluated to the criteria herein.
