Grounding is necessary, especially for units using inverter circuits, in order to release charged elec-
G
tricity and electrical noise caused by high tension. Otherwise, electrical shock may occur.
Place a dedicated ground more than 2 meters away from other grounds and do not have it shared
G
with other electric appliances.
