2.3.4 UV Sources
The printer has two UV sources which operate while printing.
• Looking at the UV light with the naked eye is dangerous. Never look directly at the UV light source.
• When working near active UV lamps, you must wear suitable anti-UV goggles that conform to international standards.
• When printer is idle at home position, the UV shutters are closed; the UV bulbs turn off automatically after 20 minutes idle.
• The printer can print only if the hood is closed.
• The hood is equipped with transparent UV-blocking screens. The UV radiation is contained by the hood and by the opaque PVC
panels installed along the top edge at the rear side of the printer.
• Before servicing the UV lamps, allow them ample time to cool down. Contact with the hot lamps can burn the skin.
2.3.5 Electrical Hazards
Various printer components are powered by electricity (1-phase 230VAC):
• The PC
• The motor drivers
• The UV bulb assembly
• In addition, within the printer AC voltage is are converted to DC voltages of 5V, 24V and 48V, and distributed to various points.
Contact with any of these voltages may cause electrical shock and burns.
• Electrical hazard is minimized as follows:
• Circuit breakers: Over-current and over-voltage activate a circuit breaker at the main input and at each AC voltage contact
point within the printer.
• In case of an overload, the circuit breaker is switches off the printer. The printer’s operator is authorized to open the cabinet
door to reset a circuit breaker if it triggers. To prevent unauthorized opening of the cabinet, the cabinet door is locked by a
special key. Only a certified EFI technician is authorized to remove the plastic cover to access the main electricity panel.
This can be done only after the main power is switched off.
• Safety labels on each electrical cabinet door and near all AC contact points.
• By proper grounding of all electrical circuits.
• By safety labels on each electrical cabinet door or panel.
