3. Safety Notes
Caution!
Power plugs may only be plugged into an
outlet equipped with a grounding contact.
Do not interfere with the grounding function
by using an extension cord without a ground
wire. Any interruption of the ground wire in-
side or outside of the device, or release of
the ground wire connection, can cause the
device to become hazardous. Intentional
ground interruption is not permitted!
Caution!
Peripheral devices with their own or sepa-
rate power supplies that are connected to
the microscope can have the same protec-
tive conductor potential by connecting them
to the ground screw on the back of the Leica
CTRxxxx electronics boxes. For connections
without a ground connector, Leica Service
must be consulted.
Caution!
Never use any fuses as replacements other
than those of the types and the current rat-
ings listed here. Using patched fuses or
bridging the fuse holder is not permitted. The
use of incorrect fuses may result in a fire
hazard.
