ZEISS 5 First Operating Steps | 5.2 Switching On the Microscope System
Before energizing the microscope make sure that the following safety warnings have been read
and fully understood by the person operating the microscope:
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.
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
Hazardous voltages inside the microscope
Contact may cause electrical shock or burn.
Hazardous voltages are present inside the microscope as long as the power cord is plugged in
or as long as the Main Switch of the EMO Circuit is in the ON position.
To completely cut off the microscope from any mains power:
4
with installed EMO Circuit set the Main Switch to the OFF position.
4
without EMO Circuit unplug the power cord by unplugging the CEE connector from the
CEE FEMALE RECEPTACLE of the mains supply.
WARNING
Restart after emergency off
If the reason for the emergency off is not eliminated, it may be dangerous to restart the micro-
scope.
4
If the microscope has been de-energized due to an emergency, ensure that the reason for
the emergency off does not exist anymore.
4
Make sure it is safe to energize the microscope.
Prerequisite
ü If the Emergency OFF (EMO) circuit is not installed:
The microscope was de-energized by unplugging the CEE connector from the mains supply.
ü If the EMO circuit is installed:
The microscope was de-energized either by turning the
Main Switch to the OFF position or
by pressing the EMO button.
Procedure 1. Verify that the main shut-off valves for nitrogen at the facility installation are operable.
à
Otherwise unlock and open the main shut-off valves.
