Grounding
To avoid electric shocks and minimize the influences of external noise, the installed devices must
be grounded to the protective grounding system which complies with the safety standards, the
electrical installations standard, and the power distribution system of the country or the region.
As for the protective grounding systems, the meshed grounding systems described in IEC 60364,
IEC 62305 and IEC 61000-5-2 can be applied. A protective device is to be installed in compliance
with the rules and regulations, in order to prevent electric shocks caused by a ground fault.
