The Figure 4 Modular was designed to minimize operator exposure to electrical hazards during normal operations. Do not remove any panels or other parts of the Figure 4 Modular casing. All exposed electrical circuits are contained within limited-access cabinets. This is to separate the operator from service and maintenance areas. Only 3D Systems Service Personnel should access the electrical panels. 100-240VAC power is present in multiple locations throughout the system. Whenever performing maintenance procedures, power down the machine and restrict AC power if possible.
