Risk of death from 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.
• Only use temperature sensors that fully comply with the specifications of the electrical
• If safe electrical separation cannot be guaranteed (for linear motors or third-party
