ZEISS
WARNING
High leakage current
High leakage currents are present in the microscope. Contact may cause burn or electrical
shock.
4
Ensure proper grounding. For more information, refer to the Installation Requirements
document.
4
Do not operate the microscope without the separate ground connection.
WARNING
Residual voltage at the mains plug
After unplugging the mains plug residual voltage is present at the pins of the plug which may
cause electrical shock.
4
After unplugging the mains plug wait at least 5 s before touching the pins of the mains
plug.
2.3.5 High Pressure Hazards
WARNING
High pressure in gas cylinders
Gas cylinders containing for example nitrogen or compressed air have a high internal pressure
of approximately 200 bar. If not properly handled, the contained gas can abruptly escape and
cause the gas cylinder to move in an uncontrollable manner.
4
Observe all safety labels on the gas cylinders and all safety instructions given by the gas
cylinder manufacturer.
4
Always operate gas cylinders in an upright position and secure them so they will not tip
over.
4
Before transporting gas cylinders, place protective caps on them.
2.3.6 Magnetic Field Hazards
WARNING
Malfunction of medical devices near ion getter pumps
Magnetic fields present at the ion getter pumps may disturb the function of medical devices.
The magnetic fields are also present if the microscope is switched off.
If you wear medical implants that are susceptible to magnetic fields (e.g. cardiac pacemakers),
do the following:
4
Keep a distance of at least 30 cm from the ion getter pumps.
4
Follow the safety instructions provided by the pump manufacturer.
