2.3.2 Terminal arrangement and screw specifications
The figures below show the arrangement of the main and control circuit terminals which differs
according to inverter type. The two terminals prepared for grounding, which are indicated by the
symbol
G in Figures A to D, make no distinction between the power supply side (primary circuit)
and the motor side (secondary circuit).
