Leica lamp housing and mercury burner

1. Safety concept

The Leica 106 z lamp housing is the light source for the
fluorescence stereomicroscope Leica MZ16 FA as well as the
fluorescence module for Leica stereomicroscopes. The
Leica lamp housing is used with 100W or 50W mercury burners,
their corresponding supply units and stray-light protection.

In particular, please note

• the safety instructions in this user manual

• the safety instructions for handling electrical devices
in the user manual M2-105-0 (M series) and M2-116-5
(Leica MZ16 FA)

• the user manual and safety instructions for the
ebq 100 supply unit

• the user manual and safety instructions provided by the
lamp manufacturer, and, in particular, the section on how to
proceed if a lamp breaks and releases mercury.

• The stray-light protection on the lamp housing prevents
irradiation of the hands.

• UV protection screen in front of the object level prevents the
user from looking directly into the UV rays.

• UV filters in the observation beam path protect the eyes.

• Automatic shutter locking during rotation of the filter chang­er, observation without fluorescence and removal of the filter
holders prevents UV radiation from reaching the eyes.

• Filter holders without transponders in the free positions of
the rapid filter changer prevent direct UV radiation from
reaching the eyes.

Lamp housing

The Leica MZ16 FA fluorescence stereomicroscope and the
fluorescence module for Leica stereomicroscopes may only be
used in combination with the Leica lamp housing for 100W or
50W mercury burners, their corresponding supply units and
stray-light protection.

Leica Microsystems accepts no liability for damages
resulting from the use of lamp housings from other
manufacturers.

High-pressure mercury burner

• To minimize the risk of explosion, replace a discolored high­pressure mercury burner promptly when it has reached the
end of its rated life. Follow the manufacturer’s specifications
and the minute meter on the supply unit!

• Allow the high-pressure mercury burner to cool off before
replacing it to prevent the possibility of severe burns:

Burn hazard

• Dispose of used mercury burners as hazardous waste.

• Follow the user manual and safety instructions provided by
the lamp manufacturer, and, in particular, the section on how
to proceed if a lamp breaks and releases mercury.

• Do not remove the mercury burner’s dust cover until after you
have installed the lamp. Be very careful to avoid getting
fingerprints on the lamp.

• After installing the mercury burner, adjust it exactly as
described. Never let the bright tips of the electric arcs, the
focal spots, cross when projected:

Hazard of explosion from overheating

• When transporting the equipment, remove the high-pressure
mercury burner, transport it in its original packaging and pro­tect moving parts in the lamp housing using the transport an­chors (which should be stored in a safe place for future use).

Leica Microsystems assumes no liability for incorrectly
installed or improperly used high-pressure mercury
burners.

Supply units

The 100W mercury burners are powered by the ebq 100 supply
unit.

Read the separate instruction manual provided with this
supply unit.

The supply unit for 50W mercury burners
is described in this manual.

For the ebq supply unit: only fuses of the specified type
with the listed rated current may be used. Using other
fuses or bridging the fuse holder is not permitted. Danger
of fire!

Always unplug the power plug of the supply unit from the power
supply:
– when installing and disassembling the lamp housing
– before opening the lamp housing
– when replacing the high-pressure mercury burner and

other parts, such as the heat-absorbing filter or the
collector

– during maintenance work on the supply unit.

After switching on the supply unit, new mercury burners
must be adjusted immediately.
There is a danger of overheating for mercury burners that
are not adjusted.
Danger of explosion.

Notice of dangers

• Never open the lamp housing when the lamp is switched on.

Eye hazard.

• Never open the lamp housing when it is energized.
Disconnect the power supply.

• Disconnect the lamp housing from the power supply when
assembling it. Disconnect the power plug and power supply.

Danger of explosion, UV radiation, danger of blinding.

• Before opening the lamp housing, allow it to cool off for at
least 15 min.

Danger of explosion, danger of burns.

• Never cover the air duct on the lamp housing.

Danger of fire!
