Hazard description
In all stages of service life, electrical hazards may
occur which endanger the entire staff of the system
operator and service personnel. In case of a short
circuit in the device, the electric arc may provoke a
fire/an explosion. In case of fault (e.g. insufficient
cooling), the lamps or the housing may become
overheated. The hot surface may lead to an ignition
/ explosion of the ambient air.
Protection aim
Avoiding the fire and explosion hazard.
Protective measures
Only regular maintenance work can prevent the
components from burning.
When electrical / electronical components are used,
there can always be a short circuit igniting the
component.
Regular maintenance can minimize the risk but
cannot eliminate the risk completely.
Residual risk
Only regular maintenance work can prevent the
components from burning. Protective measures
against fire and explosion hazards in connection
with the IR radiation and vapors are explained in
detail in the operating manual and in the calculation
and are not looked at closely in this document.
4. Installation of the system
The device must only be commissioned
and operated by qualified persons.
Qualified personnel within the scope of
safety-related instructions are persons
who are allowed to install, ground and
mark devices, systems and electric circuits
according to the safety standards.
Due to high voltage required for the operation of
lamps, the covers of the ballast and the hood of the
dryer must not be opened by unauthorized persons.
Wear UV safety goggles when performing any
measuring and inspection work.
To avoid overheating of components, first, switch off
only the lamps at the end of the workday.

Rear side UVC-5
The power supply cable (230 V/50 Hz) is located on
the rear side of the mini laboratory dryer. Before
connecting the device, observe the technical data
indicated in this operating manual.
The lamp unit of the mini UV laboratory dryer can
be mechanically adjusted by means of screws. For
safety reasons, the height should only be adjusted if
the device is off. Using suitable protective devices,
the surrounding area is protected against UV
radiation to the greatest possible extent. Due to the
design, UV radiation is emitted at the inlet and
outlet. Avoid unnecessary light emission by
positioning the height adjustment to the lowest
possible position. Take appropriate protective
measures to protect the device environment against
UV radiation (e.g. protective curtain, cover, etc.).
Make sure that the supply air and exhaust air
