* HZI855 controller includes two bi-stable relays with backup energy, when the controller loses all sources of power supply outputs 5 and 6 will automatically
activate (NO contact will close and NC contact will open). This is a safety feature designed to ensure power availability to the load in Main-Genset or Genset-Genset
application by forcing generators to start in case of total power loss. It is highly recommended to configure the outputs 5 and 6 to take benefit from this function.
