Safety guidelines
Note
At least one additional digital module is required for this control function.
Note
Two current settings must be set for the pole-changing starter:
• I
• I
Depending on the current range, the current can in many cases be directly measured at both
speeds with a single current transformer. Otherwise you will need two external current
transformers appropriate for the relevant speed (e.g. 3UF18 with a 1 A secondary
transformer rated current), whose secondary cables must lead through the current
measuring module within the range 0.3 to 3 A. The current setting I
converted according to the secondary currents of the external transformers. For more
information, see Chapter Overload protection (Page 34).
