Caution
Risk of equipment damage. A DC-powered system uses –48 VDC power, is powered from a
fuse panel, and can be damaged by overloaded circuits. To reduce the risk, ensure that the
fuses in the external fuse panel are suitably rated for the installation in accordance with the
National Electrical Code (in the United States) or applicable local jurisdiction (outside the
United States) installation requirements.
