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.
Extraneous-conductive parts (metallic pipes, fences, ladders, handrails, etc.) with 2.5 m of the Printer or Controller should be connected to the protective bonding circuit.
Anywhere on the machine where you see an electrical component labeled with an "N," this indicates neutral conductivity.
Both the Figure 4 Modular Printer and Controller are meant for use in a type TN power distribution system.
