2.8.3 Operation of the line connection components via an autotransformer
An autotransformer can be used for voltage adaptation in the range up to 3AC 480 V +10%.
Caution
To ensure safe electrical separation, an isolating transformer must be installed with voltages
greater than 3AC 480 V +10%.
Applications:
• The motor insulation must be protected from excessive voltages.
• The active line module must provide a stabilized DC link voltage. It can be in the range
380 V to 415 V.
