G Ground terminal This is the ground terminal. Connect this terminal to the ground.
200-V class should be connected under type-D grounding conditions;
400-V class should be connected under type-C grounding conditions.
For 200-V class models with a capacity of 3.7 kW or lower and 400-V
class models with a capacity of 4.0 kW or lower, the ground terminal
is located on the cooling fin.
