often in a particularly heavily polluted atmosphere). Also, while changing the lamps, a careful check should be made of the high voltage leads to make sure that no deterioration has occurred. Dirty contacts may cause a potential hazard. Danger Accessing and cleaning electrical components must be done only after the machine has been shut down and disconnected from mains power. High Temperatures UV system operates at very high temperatures and the inside components become very hot during machine operation, which may cause personal injury. Therefore, when maintaining the equipment, a reasonable time (15 minutes) should be allowed before access is attempted. Safety UV Curing UV Radiation UV radiation is generated from UV lamps and can be harmful if operator exposure exceeds recommended levels (see Permissible UV Exposure Levels on page 17). Danger To avoid exposure, always work with the UV flaps in the "up" position (see Figure 1-7. UV lamp housing UV flaps Figure 1-7 UV Flaps in the "Up" Position All equipment is adequately guarded, shielded and interlocked to prevent accidental operator exposure. Equipment should be annually checked for UV radiation levels. Radiation is in the wavelength bands A, B, and C. Exposure to UV radiation can result in: 14 HP Scitex Industrial Presses Essential Health and Safety Instructions
