B.1
Why is a ground connection required?
You must grounding the SAILOR 900 Ka 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.
