2.11 Grounding/ earth points
All parts of the system must be fully and correctly connected to a proven earth point prior to
connecting any source of AC power.
The system must never be switched ON or operated with an earthing point disconnected.
Connection point: All Kelvin Hughes equipment is fitted with a single protective earth connection
point which is indicated on the mechanical installation drawings.
Conductivity tests: During installation and maintenance, the earth connections must be tested for
conductivity using a high current impedance meter such as a Megger or
similar.
Wrist Straps: Fully isolate and mechanically disconnect all sources of AC before attaching
ESD protective wrist straps to the various points in the system.
