9. M125S20 Page 9 8. Cautions X-ray tube ass’y should have the X-ray limiting equipment mounted on the X-ray port to protect unnecessary radiation. X-ray tube ass’y is not allowed is not allowed to use in the atmosphere of flammable or corrosive gas. If the input power exceeds X-ray tube ass`y specification, it cause the over temperature of anode, insert tube glass shatter, housing sealing parts rupture, human injury including burns due to hot oil escape and fire accident due to flaming anode target. The X-ray generator should have a protective function which manages input power to be within X-ray tube ass’y specification. X-ray tube ass’y is covered with lead inside tube housing to protect unnecessary radiation. The lead is harmful for human health. Dispose the scrapped products according to the requirement of local regulation. X-ray tube ass’y has insulating oil contained for high voltage stability. The insulating oil is poisonous for human health. If it is exposed to the non-restricted area, it should be disposed as following to the local regulation. According to the operating conditions, the filament characteristics might be changed to lead to the over rate exposure to X-ray tube ass’y. To prevent the X-ray tube ass’y from being damaged, please adjust the tube current regularly. Please don’t touch on X-ray tube ass’y just after operation due to high temperature. If any malfunction of the X-ray tube ass’y is noticed, please contact to us immediately. Rotating Anode X-ray Tube Ass’y Spec.
