Before to supply the thyristor unit:
• verify that load current equal or less than nominal;
For resistive load

• 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 and syncronized to main voltage!!!;
• Fan voltage equal than nominal (220-240V std, 110-120V 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.
