3.1 Unpacking, installation site, assembly
tools, safety information
Unpacking:
Please compare the delivery carefully with the
packing note, delivery note or invoice.
We strongly recommend that you keep a copy of
these documents with the manual, so that you
have information on the time and scope of the
delivery later when ordering more equipment or
when the microscope is serviced.
Make sure that no small parts are left in the
packing material.
Some of our packing material has symbols indi-
cating environment-friendly recycling.
n.b.!
When lifting the microscope out of the packaging
do not touch any movable, mechanical compo-
nents.
When putting the microscope on the desk and
adjusting its position, make sure not to damage
the sensitive damping feet on the underneath of
the microscope.
n.b.!
Do not connect microscope and peripherals
to mains yet (see section 3.2, Assembly)
Installation site
Make sure that the workplace is free from oil and
chemical fumes. Vibrations, direct sunlight and
major temperature fluctuations should be avoi-
ded. For ergonomic microscopy we recommend
a stable desk (about 70–80 cm high) and a com-
fortable, adjustable chair.
Assembly tools
Installation and assembly of the microscope
should preferably be carried out together with a
member of Leica sales or service staff.
Only a few ordinary screwdrivers are required for
assembly, and these are supplied with the
microscope.

Safety information
This instrument of safety class 1 has been built
and tested according to EN 61 010-1/IEC 1010-1
safety standards for electrical measurement,
control and laboratory equipment.
n.b.:
To keep the microscope in this safe condition,
it is essential to note the advice and warnings
given in this manual.
The mains plug must only be inserted into a
grounded outlet.
If an extension cord is used, it must be grounded
as well. Any interruption of the ground connector
inside or outside the microscope or disconnec-
ting the ground connector can render the micro-
scope potentially dangerous. Intentional sever-
ance is forbidden!
n.b.:
Using the ground connection, any accesso-
ries connected to the microscope which have
their own and/or a different power supply can
be given the same ground conductor poten-
tial. Please consult our servicing personnel if
you intend to connect units without a ground
conductor.
Make sure that only fuses of the specified type
and rating are used as replacements. It is forbid-
den to use mended fuses or to short-circuit the
fuse holder.
n.b.:
The instruments and accessories described in
this manual have been safety-tested and
checked for possible hazards.
Before modifying the instrument in any way or
combining it with non-Leica products not
dealt with in this manual, it is essential to con-
sult the Leica agency for your area or the main
factory in Wetzlar!
Any unauthorized alteration to the micro-
scope or use for which it was not intended will
automatically terminate any warranty claim.
11
n.b.:
The electric accessories of the microscope
are not waterproof. If water gets inside them,
it may cause electrical shock.
Do not put the microscope and its accessories
near a water tap or anywhere else where
water may get inside them.
n.b.:
Before changing fuses or lamps, always turn
the mains switch off and disconnect the mains
cable.
n.b.:
Protect the microscope from major tempera-
ture fluctuations. These may lead to conden-
sation which can damage the electric and
optical components.
n.b.:
Avoid skin contact when using immersion oil!
Ask the supplier for a safety information
sheet!
