WARNING
Danger to life due to electric shock in the event of voltage flashovers at the temperature
sensor
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
•
Use temperature sensors that fully comply with the specifications of the safety isolation.
