NOTICE
Risk of motor overheating for incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats.
• Make sure that you connect the KTY temperature sensor with the correct polarity.
Note
There are two ways of connecting the temperature sensor:
1. via X120, terminals 1 and 2
2. via X23, pins 1 and 8
