Grounding and RF protection

F.1 Why is grounding required?
F.1.1 Reasons for grounding
Grounding the FV-110 system is required for at least two reasons:
• Safety: Lightning protection of persons and equipment.
• Protection: ESD (ElectroStatic Discharge) protection of equipment.
F.1.2 Safety
First of all grounding of the system is required for safety reasons. In the event of a
lightning strike at the ADU a proper grounding of the system will provide a low resistance
path to divert the strike discharge to seawater.
F.1.3 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.
