Appendix B
Ground and RF protection B
This appendix has the following sections:
• Why is a ground connection required?
• Recommendations
• Alternative ground for steel hulls
• Alternative ground for aluminum hulls
• Alternative ground for fibre glass hulls
• Separate ground cable
• RF interference
• Jumper cable for grounding
B.1 Why is a ground connection required?
You must grounding the SAILOR 100 GX system for at least two reasons:
• Safety: Lightning protection of persons and equipment.
• Protection: ESD (ElectroStatic Discharge) protection of equipment.
B.1.1 Safety
A ground connection of the system is required for safety reasons. In the
event of a lightning strike at the ADU a proper ground connection of the
system will provide a low resistance path to divert the strike discharge to
seawater.
B.1.2 ESD Protection
The ESD protection circuits in the ACU rely on proper grounding of the
system in order to work properly. Otherwise sensitive circuits within the
ACU might be damaged due to ESD when you are handling the
equipment.
