2.9.3 Operation of the Line Connection Components via an Autotransformer
An autotransformer can be used to adapt the voltage in the range up to 3-ph. 480 V AC
+10 % or 1-ph. 240 V AC +10 %.
CAUTION
To ensure safe electrical separation, an isolating transformer must be used for voltages
greater than 3-ph. 480 V AC and 1-ph. 240 V AC.
Application example:
The motor insulation must be protected from excessive voltages.
