The temperature sensor is part of an SELV circuit, which can be destroyed if a high voltage
is applied. The temperature sensor is designed so that the DIN/EN requirement for
"protective separation" is fulfilled.
Due to the thermal coupling time of the temperature sensor, high short-term overloads
require additional protective measures.
NOTICE
Destruction of the motor for a thermal critical load
A thermal critical load, e.g. high overload at motor standstill, can destroy the motor.
• Use an overcurrent relay, for example, as an additional protective measure.
