Axioskop 2 plus INTRODUCTIONAxioskop 2 mot plus Notes on instrument safety Carl ZeissB 40-075 e 10/03 0-9The Axioskop 2 plus and Axioskop 2 mot plus microscopes, including original accessories, may only beused for the microscope techniques described in this manual.Particular attention must be paid to the following warning notes:The manufacturer cannot assume any liability for any other applications, possibly also involvingindividual modules or single parts. This also applies to all service or repair work which is notcarried out by authorized service personnel. Furthermore, this forfeits all the claims againstwarranty.The power plug must be inserted in a socket featuring a grounding (earth) contact. Thegrounding effect must not be made ineffective by an extension cable which does not have aprotective ground wire.If it is established that protection measures are no longer effective, the instrument must beswitched off and safeguarded against inadvertent operation. Please contact a Zeiss serviceagency or Carl Zeiss Microscopy Service for repairing the instrument.☞ The power unit which is integrated in the stand of the microscopes permits the use of linevoltages in the range between 100 and 240 V ± 10 %, 50 / 60 Hz, without having to changethe voltage on the instrument.The ballasts for the HBO 103 (ebg 100 dc) or XBO 75 (ebx 75 isolated) are designed for the 90to 250 V AC, 50 to 60 Hz range. The instruments adapt automatically to the available linevoltage. There is no need to change the voltage.However, the transformer for the HBO 50 must be set manually to the correct voltage (100,110, 120, 127 or 230, 240 V), and the correct frequency must be preselected (50 or 60 Hz).Before switching on the instrument, check whether it is suitable for the line voltage present.Before switching on the instrument, check whether it is suitable for the line voltage present.Always disconnect the instrument from the line before opening the instrument and beforechanging the fuses.Make sure to use only fuses of the rated power required. The use of makeshift fuses and theshort-circuiting of the fuse holders are not permitted.
