– Use 60/75 °C copper conductors only:
– [X6], motor connection
– [X9], load and logic voltage
– Use in an environment with pollution degree 2 (or better).
– Maximum surrounding air temperature: 50 °C
– With correct parameterisation of the nominal motor current, the motor is protected against over-
loading by the I²t monitoring function.
– For the load voltage supply, the use of a suitable fuse is recommended in accordance with the
following table.
