The Axioscope 5/7/Vario
microscopes and their original accessories may be used only for the microscopy
procedures described in this operating manual.
The following guidelines are especially important:
CAUTION
The microscope may only be plugged into an electrical outlet equipped with a safety contact.
The safety feature must not be disabled by using an extension cord which does not have a
protective ground conductor.
CAUTION
Whenever it becomes apparent that any of the safety mechanisms are out of order, the
microscope must be switched off and protected from any inadvertent use.
Please contact the ZEISS Service Department or the Carl Zeiss Microscopy Service before
switching the microscope on again.
CAUTION
The stands are equipped with integrated power supply units. These units adapt to a voltage
range of 100 to 240 V and a frequency range of 50 to 60 Hz. No further voltage adjustment
is necessary on the microscope itself.
The 12 V DC 100 W external power supply unit for HAL 100 covers a voltage range from
100 to 127 V AC and 200 to 240 V AC
±
10%, and a frequency range of 50 to 60 Hz. It
adapts automatically to the applied voltage.
The 24 V DC 30 W external power supply unit for Axioscope 5 Vario covers a voltage range
from 100 V to 240 V and a frequency range of 50 to 60 Hz.
The power supply units for the HBO 100 adapt to a voltage range from 100 to 240 V AC and
a frequency range of 50 to 60 Hz. They adapt automatically to the applied voltage. No further
voltage adjustment is necessary.
Before you switch on the instrument, please verify that the voltage you are about to use is
suitable.
CAUTION
Always disconnect the microscope from the power supply before you open it or change a
fuse!
Make sure that the fuses are suitable for the applied nominal current. Never use any
makeshift fuses and do not short-circuit the fuse holders.
CAUTION
The microscopes do not have any special safety devices to protect users from acid or from
potentially infectious, toxic, radioactive or other samples that may be hazardous to your
health. Compliance with all statutory requirements, especially national accident prevention
regulations, is required when handling such samples.
