It is mandatory to install two devices:- 1) one device for
voltage adjustment 380v/220v 2)second device for HZ
Converter from 50hz/60hz, but as per technical knowledge
better to change them to suitable motors for 380 Volts / 50
HZ as the cost of Transformers (9nos.) and frequency
converters(50 HZ./60 HZ.) is more than the requirement.
