If the application requires a “floating” galvanic installation, such as in marine applications with only IT power supply available, and high voltage insulation from AC power and/or signal lines to the chassis, do the following:
  1. Use a 500 VA isolation transformer in the AC power input and bond the chassis ground to the installation platform (the metal hull/deck).
  2. Connect the communication line to the data receiving system through a galvanic signal isolator or use fiber-optic communication.
