At full load, set the motor protection switch to the rated current (see rating plate). At partial
load, it is recommended to set the motor protection switch to 5 % above the measured cur-
rent in the duty point.
The motor protection setting depends on the installation:
▪ Motor protection installed in the motor line: Set the motor protection to 0.58 x the rated
current.
▪ Motor protection installed in the power supply cable: Set the motor protection to the rated
current.
The maximum start-up time in star connection is 3 seconds.
At full load, set the motor protection switch to the rated current (see rating plate). At partial
