To change the capacitance to
Large, fix to A with the grounding
capacitor screw.
To change the capacitance to
Small, fix to B with the grounding
capacitor screw.

Warning
Prohibited
In case of one phase grounding system (A three-phase supply power is connected in delta),
isolated neutral system, or high resistance grounding system, do not change the connection of
grounding capacitor before factory setting.
If connection changed (this means the capacitance is increased), the capacitor may become damaged.
Note: If a neutral grounding system is used, changing the connection of the grounding capacitor as shown in the
figure at the top (changing the capacitance from Small to Large) makes the inverter compliant with the EMC
directive.
