Supplementary devices
Depending on the order, various supplementary devices can be installed or mounted. These
include sensors for bearing temperature monitoring or winding monitoring, for example.
Risk of explosion during operation due to too high surface temperature
This can result in death, serious injury, or material damage.
• Prevent the maximum surface temperature from being exceeded by maintaining the
specified operating conditions.
• Monitor the coil temperature. Use the temperature sensor that is built into the stator
winding for this as specified on the rating plate or extra rating plate.
