The following terms and symbols are used in this manual for particularly important

Special information, regulations and restrictions concerning the prevention of

WARNING!
The machine should only be used if it is in technically perfect condition and in
compliance with the regulations. Pay attention to safety and the operating
instructions. It is especially important to immediately rectify all faults which could
impair safety. Proper machine operation includes following the instructions in the
operating manual and complying with the inspection and maintenance conditions.
In order to make operating our machines as easy as possible for you, we would
like to briefly inform you of the most important safety regulations. If you comply with
these regulations, you will be able to use our machine in a safe and quality-
assuring manner for a long time to come.
WARNING!
When the power supply is switched on, no supply lines may be connected or
disconnected or signals checked.
The DC condenser of the frequency converter is also still charged when the power
supply is switched off. To avoid the danger of injury to personnel or damage to
equipment, the frequency converter must be disconnected from the mains before
maintenance work is performed. Please wait at least five minutes until all LEDs
have stopped glowing.
A voltage withstand check may not be conducted on any component of the
frequency converter. The frequency converter contains semi-conductors which are
not suitable for such voltages. The control unit may not be removed when the
power supply is switched on. In addition to this, the circuit boards may not be
touched when the frequency converter is connected to the mains.
