1. Remove the connection box cover.
2. Mount (glue) an additional PT100 temperature sensor close to the end of the windings at the opening
where the signal cables are routed inside the electric machine enclosure (inside the connection box
lower part). Use resin/glue specified for correct temperatures (Temp.class in the rating plate, class F /
155ºC).
3. Connect the PT100 sensor to the low voltage connector (replace the failed sensor connection by the
new connection).
4. Remount the connector box cover.
When reading the temperature (resistance) values from the additional sensor, add +15ºC to the
measured value. This gives more correct estimation of the inner temperature of the electric machine. In
case of the temperature measurement failure and using additional temperature sensor, replace the
electric machine as soon as possible, but no later than in two months.
