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.

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!
