• verify that there is no short circuit on load;
• verify that main voltage equal or less than nominal;
• verify that all auxiliary connections are right;
• fan voltage equal than nominal (230V std , 110V optional)
After which supply thyristor unit giving the maximum input signal and verify that load current is
equal or less than thyristor unit nominal current.
Warning: this procedure can be done just by specialized personnel.
The thyristor unit is delivered configured and tuned in line with customer
requirements. If it's necessary to change on site the configuration, procede as below
specified.
