• Electrical appliances must be kept out of the reach of children. Be particularly
careful if children are present. Children are not aware of the hazards involved
in handing electrical appliances improperly. Children could attempt to poke
objects into the appliance. There is a life-threatening danger of electrocution.
• Do not leave the appliance unattended while operating it.
• Never place the appliance on an unstable or movable surface. Persons could
be injured or the appliance be damaged by falling down.
• When using a rack, make sure it is in a stable position and is transported
securely. Installation on uneven, slanted surfaces or stopping the rack
abruptly during transport can result in the rack overturning or appliances
falling from or out of the rack and injuring people.
• Live components can be exposed by opening covers or removing components
(unless this can be done without tools). Contact points can also be live. If the
appliance has to be opened in order to calibrate, service, repair or replace
components or assemblies, all of its poles must be disconnected from all
sources of voltage first. If the appliance has to be kept open and under
voltage during maintenance or repairs, this work may only be carried out by a
specialist who is familiar with the risks involved and the relevant regulations.
• Never connect the appliance directly after transferring it from a cold to a
warm room. The condensation water that might occur could destroy the
appliance or result in an electric shock. Allow the device to reach room
temperature before connecting it. Wait until the condensation water has
evaporated. This can take some hours.
• Do not place any naked flames such as those of burning candles on or next to
the appliance.
• Do not place the appliance on soft surfaces such as carpets or beds. Do not
cover the air vents of the appliance. Do not obstruct the air circulation with
objects such as magazines, table cloths or curtains. This prevents the
dissipation of heat from the appliance and can result in overheating.
• Only use the appliance in a moderate climate, not in tropical environments.
• All persons involved in operating, installing and servicing the appliance and
putting it into service must be trained and qualified accordingly and observe
these operating instructions.
• Defective mains cables may only be replaced by specialists. Danger of
shock hazard!
• Do not leave the packaging material lying around carelessly since it can
become a source of danger for children playing with it.
• The accident prevention regulations and the regulations of the employers'
liability insurance association should be observed at commercial institutions.
• If you are not sure about the correct connection or if questions arise which are
not answered by the operating instructions, please do not hesitate to contact
