Safety information

Safety notes
Missing covers
All covers which are designed to prevent active or rotating parts from being touched, or
which are necessary to ensure correct air guidance and thus effective cooling, must be
installed prior to start-up.
Dangerous, high voltages
Work on high-voltage systems may only be carried out by specialist personnel. During the
commissioning of the 1FW4 motors, the personnel must be familiar with and observe:
• These operating instructions
• The hazard and warning information on the motor and in these operating instructions
• The electrical data sheet
• The motor dimension drawing
• The shaft dimension drawing
• The test certificates
• The commissioning instructions for the converter
Operational electrical equipment and motors have parts and components which are at
hazardous voltage levels.
Driving the motor via the system
If it is possible when operating the system to passively drive the motors, we recommend the
use of short-circuit-proof cables. Optionally, you can use circuit breakers near the motor for
protecting the sections of cable during a short circuit. During a short circuit of a cable or
converter, a short-circuit current is driven by the induced voltage which is present at the
motor terminals due to the rotation of the permanent magnet rotors.
