Installation notes

  • Size the system so that the normal consumption is as close to 80-90% of the rated power of the power supply as possible
  • Use only 1 power supply to power all modules of the system
  • If it is necessary to use 2 or more power supplies, they must have GNDs connected to each other, or ideally an optical isolator should be used
