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.

Encoders
4.1.2.1
Encoders for 1FT7 motors
NOTICE
Destruction of the encoder when incorrectly handling ESD parts and components
Encoders are ESD components.
• Comply with the regulations for handling parts and components that can be destroyed
by electrostatic discharge, see Equipment damage due to electric fields or electrostatic
discharge (Page 16).
The following encoders can be used with the 1FT7.
