... Power-Up Procedure When 3-phase input power is first switched on, PWM inputs to the IRPT2051 must be inhibited (held high) until the protection latch circuitry is reset. To reset this latch before inverter start- up, RESET pin on J6 connector must be pulled down low for at least 2 µsec. This will set the FAULT feedback signal high. ...
