INTRODUCTIONCarl Zeiss Safety Guidelines Axio Scope.A110 M60-2-0007 e 05/08The microscope Axio Scope.A1 and its genuine accessories may only be used for microscopy methods asindicated in this manual.The following guidelines are especially important:The manufacturer admits no liability if the microscope, its components or single parts, are usedin any different manner. Liability is also excluded for any service or repair work performed bynon-authorized personnel and any rights to claims under guarantee expire.The microscope may only be plugged into an electrical outlet equipped with a safety contact.The safety aspect must not be disabled by using an extension cord which does not have aground wire.Whenever it becomes apparent that any of the safety mechanisms is out of order, themicroscope must be switched off and protected from any accidental use. Please contact theZeiss Service Department or the Carl Zeiss Microscopy Service before switching the microscopeon again.The lower stand parts for LED illumination and those with integrated HAL 50 illumination areequipped with a power supply unit integrated in the stand. This unit adapts to a voltage rangeof 100 to 240 V ±10 %, 50 / 60 Hz, no further voltage adjustment is necessary on themicroscope itself.The auxiliary power supply unit SNT 12 V DC 100 W for HAL 100 covers a voltage range from100 to 240 V AC ±10 %, 50 to 60 Hz. It adapts automatically to the applied voltage.The transformers for the HBO 100 adapt to a voltage range from 100 to 240 V AC, 50 to60 Hz. They adapt automatically to the applied voltage. No further voltage adjustment isnecessary.However, the transformer for the HBO 50 must be adjusted according to the applied voltage(100, 110, 120, 127 or 230, 240 V). Please do not forget to adjust the power frequencyaccordingly (50 or 60 Hz).Before you switch on the microscope, please verify that the voltage you are about to use issuitable.Always pull the plug before you open the microscope or change a fuse!Please make sure that the fuses are suitable for the applied nominal current. Never use anymakeshift fuses and do not short-circuit the fuse holders.The microscopes Axio Scope.A1 do not have any special safety fixtures to protect from acid,potentially infectious, toxic, radioactive or other specimens potentially hazardous to your health.All legal requirements, especially the national regulations for the prevention of accidents mustbe followed.
