Listed protections include input undervoltage, overheating, overcurrent and short circuit. There is no input reverse-polarity protection: check positive and negative connections before powering on. Disconnect power before changing operating mode, and follow the model-specific manufacturer wiring instructions for BTL or PBTL configuration. Do not connect outputs together except as explicitly directed by those instructions.
