Application Notes
Heater must be switched on in stages because inrush current must not exceed 300A. Connection of the second grid lead is recommended even in medium-wave operation for better heat dissipation. In industrial generators with varying loads, grid current limiting resistors (incandescent lamps) are recommended.
