Connecting the temperature sensors
NOTICE
Risk of damage to temperature-sensitive components
Some parts of the electrical motor enclosure can reach temperatures that exceed
100 °C. If temperature-sensitive components, e.g. electric cables or electronic
components, come into contact with hot surfaces, these components could be
damaged.
• Carefully ensure that no temperature-sensitive components are in contact with hot
Connecting the Pt1000 temperature sensors
Note
Pt1000 temperature sensors are not ESD components.
Connect the Pt1000 temperature sensor independent of the polarity via two-conductor
yellow cables.
You can connect the Pt1000 and PTC as follows:
● Pt1000 via SMC20 or directly at the drive system
● PTC via thermistor motor protection 3RN2013-1GW30 or a comparable device
