–
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.
