Precaution on Selecting System Components
When building a system, use components which have already obtained type approval for
marine standards. For the HMI’s PC and ENG’s PC, use generic computers (including monitors,
keyboards, mice, and other peripheral devices) which are accredited by the required marine
standards.
Precaution on Installing Components
Each component shall be installed in accordance with its installation guidance. In addition, all
components related with FCN-500 shall be installed in a metal cabinet.
• The cabinets including their doors and side panels must be made of a metal.
• Securely connect the cabinet frames and ground bosses on doors and side panels to each
other to ensure electric contacts.
• Attach noise suppression devices, such as noise filters and ferrite cores, to the cables
connecting each component.
Installation of Power-line Noise Filter
Attach a noise filter on the power line for the following components:
• FCN-500 Autonomous Controller (control unit and extension unit)
Power-line for FCN-500
Attach a noise filter in each power line of FCN-500 and external power supply unit.
Alternatively, other devices such as noisecut transformer and insulating transformer can be used
if its characteristic of noise-reducing effects is same as the following equipment. Noise filter and
external power supply unit shall be installed in the same cabinet of the connecting terminal board
for them.
The following table shows example of a noise filter.
