ZEISS 10 Technical Data and Conformity | 10.2 Installation Requirements
Parameter Requirement
Protective ground High leakage currents are present in the microscope. Therefore, the
microscope has to be connected to a separate protective ground.
An exclusive grounding connection to earth must be provided as part
of the building installation, i.e. a grounding screw terminal (Ø 8 mm)
which is directly connected to the PE of the FEMALE RECEPTACLE as
short as possible.
This grounding connection must not be common to other electrical
equipment.
A grounding wire AWG10 (≥ 5 m) is delivered with the microscope. It
serves as connection between the grounding screw terminal (Ø 8 mm)
and the microscope (Ø 6 mm).
