installation, the user must check if the group and protection class, marked on the motor label,

simultaneously.
Temperature classification of the motor depends on the internal thermal protection and it is given
on the name plate.
Under no circumstances should a lower temperature class be used to replace a higher
temperature class motor (ie. T3 should not replace a T6).
INCOMING INSPECTION
When receiving the motors, check if any damage has occurred to the packaging of the motors
during transportation. If so, immediately notify the carrier, the insurance company and supplier.
Failure to do so may invalidate any possible claims.
Inspect the following after packaging has been removed:
- Check for any damage to the motor;
- Check nameplate data to ensure correct motor has been received;
- Check if dimensions and colour are in compliance with your specifications;
- Rotate the shaft by hand to make sure it is turning freely;
- Make sure the motor was not exposed to excessive dirt and moisture during transportation and
storage.
In the unlikely event of a claim, please contact our Sales Office.
Do not use the motor when damaged.
