PROPERTY DAMAGE

Protection against motor overload is not active by default. The ETR function provides class 20 motor overload protection. Failure
to set the ETR function means that motor overload protection is not provided and property damage can occur if the motor over-
heats.

Enable the ETR function. See the application guide for more information.

1.7 Disposal

Do not dispose of equipment containing electrical components together with domestic waste. Collect it separately in accordance
with applicable local regulations.
