WARNING
The converters are operated at high voltages.
Disconnect the power supply before making any connections!
Only qualified personnel who are thoroughly familiar with all safety notices contained in the
operating instructions as well as erection, installation, operating and maintenance instructions
should be allowed to work on these devices.
Non-observance of the safety instructions can result in death, severe personal injury or
substantial property damage.
The converter might sustain serious or irreparable damage if connected incorrectly.
Voltage may be present at the power and control terminals even when the motor is stopped.
The snubber capacitors continue to carry hazardous voltage for up to 2 minutes after isolation
from the supply. For this reason, the converter must not be opened for at least two minutes
after switch-off.
When working on the open converter, remember that live parts are exposed. The unit must
always be operated with the standard front covers in place.
The user is responsible for ensuring that the motor, SIMOTRAS converter and other devices
are installed and connected up in accordance with the approved codes of practice of the
country concerned and any other regional or local codes that may apply. Special attention must
be paid to proper conductor sizing, fusing, grounding, isolation and disconnection measures
and to overcurrent protection.
These converters contain hazardous rotating machinery (fans) and control rotating mechanical
components (drives). Death, serious bodily injury or substantial property damage may occur if
the instructions in the relevant operating manuals are not observed.
The successful and safe operation of this equipment is dependent on careful transportation,
proper storage and installation as well as correct operation and maintenance.
