ATTENTION: Do not use the RPI input on the SB3000 Rectifier’s
Resolver & Drive I/O module as a method of shutting off the Rectifier.
Turning this input off stops the Rectifier’s power devices from firing.
However, the emitter-collector diodes in these power devices will still
conduct and will continue to feed the load inverter if input power is on.
Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
