– Only original Leica spare parts may be used
– Unplug the power cable before opening the supply unit.
Touching live circuits can cause injury.
Legal requirements
Adhere to general and local regulations relating to accident
prevention and environmental protection.
Conformity with European Community directive
Leica stereo-fluorescence systems and their accessories are
constructed in accordance with the latest technologies and are
provided with a statement of conformity with EC requirements.
Light source: Safety regulations
Safety measures introduced by manufacturer
– UV protection screen in front of the specimen plane prevents
direct UV radiation from reaching the eyes.
– Dummy filter carriers in the unoccupied positions of the rapid
filter changer prevent direct UV radiation from reaching
the eyes
– UV filters in the observation beam paths protect the eyes
against UV radiation.
– Stray-light protection on the underside of the lamp housing
protects the user's hands against UV radiation.
Warning
UV can damage your eyes. Therefore:
– Never look at the light spot on the specimen plane without
the UV protection screen in position
– Never look into the eyepieces unless there is an excitation
filter in the beam path
– Always keep dummy filter carriers in the unoccupied
positions of the rapid filter changer (for MZ10 F)
– Do not place the specimen on a white or highly-reflective
background.
Supply unit
• Pull the power plug of the supply unit out from the power sok-
ket:
– when assembling and dismantling the lamp housing
– before opening the lamp housing
– when changing the mercury-vapour burner and other
components such as the heat- protection filter or the collector
– when servicing the supply unit
Lamp housing
• Never open the lamp housing while the burner is switched on
(risk of explosion, UV irradiation, dazzling)
• Always allow the lamp housing to cool for at least 15 minutes
before opening it (risk of burner exploding)
• Never cover the ventilator slots on the lamp housing (risk of fire)
Mercury-vapour lamp
• Read the user manual and safety directions provided by the
manufacturer of the mercury-vapour burner, and particularly
those relating to its breakage and to the release of mercury
• Before transporting the equipment, remove the mercury-vapour
burner and place it in its original packaging. Use the transport
peg in place of the burner, to secure movable parts within the
lamp housing
• When the mercury-vapour burner has reached the end of its
nominal working life as indicated by the manufacturer’s
information and the time counter on the supply unit, change the
discoloured burner (increased risk of explosion)
• Leica declines all responsibility for injury and damage
resulting from exploding, incorrectly-fitted or incorrectly-used
mercury- vapour burners.
