DANGER
Converters contain hazardous electrical voltages, Death, severe bodily injury or significant
material damage can occur if the safety measures are not followed.
1. Only qualified personnel, who are knowledgeable about the converters and the provided
information, can install, start up, operate, troubleshoot or repair the converters.
2. The converters must be installed in accordance with all relevant safety regulations (e.g.
DIN VDE) as well as all other national or local regulations. Operational safety and
reliability must be ensured by correct grounding, cable dimensioning and appropriate
short-circuit protection.
3. All panels and doors must be kept closed during normal operation.
4. Before carrying out visual checks and maintenance work, ensure that the AC power
supply is disconnected and locked out. Before the AC supply is disconnected, both
converters and motors have hazardous voltage levels. Even when the converter
contactor is open, hazardous voltages are still present.
5. When making measurements with the power supply switched on, electrical connections
must not be touched under any circumstances. Remove all jewelry from wrists and
fingers. Ensure that the test equipment is in good conditions and operationally safe.

instructions.

the equipment. If you require other information or if certain problems occur which are not
handled in enough detail in the information provided in the Instruction Manual, please
