The warning triangle shows you an important advice. You
e
must absolutely take care of these in order to avoid dam-
ages to devices or even to persons.
The hand gives you additional advice. These refer you to
circumstances that were often disregarded and therefore
led to misunderstandings and longer search for an error.
When handling with 230 volt supply voltage and with the units supplied
by this voltage the relevant electric safety regulations must absolutely
be observed.
Please pay attention to the following general safety advice by all
means:
All devices must be installed without current. (e.g. in case of main-
tenance work).
All devices may only be put into operation if they are properly built
into the case.
Units that operate with external voltage - especially with supply volt-
age - may only be opened if they were disconnected from the volt-
age source or from the mains first.
The mains cables of the electric devices and the connection cables
must regularly be checked for damages. If you discover damages,
the concerning cables must be replaced.

The use of tools near or on covered or open circuit lines and circuit
boards as well as on and in devices that are supplied with external
power - especially with mains voltage - must be avoided as long as
the supply voltage is not switched off and the device is not made
free of voltage by discharging existing capacitors. The charge
capacitor of the switching power supply unit can be charged for a
long time in case of a failure even after being switched off.
If you use construction elements, components, assembly groups,
connections and units, you must absolutely take care of the limita-
tion values for voltage, currency and power consumption indicated
in the technical data. Exceeding those limitation values (also short-
time) may cause extensive damages.
The units, unit assemblies or connections mentioned in this opera-
tion instructions may only be used as described. If you are not sure
how to use the merchandise, please ask a specialist.
