To change the capacitance to Large, secure the upper end of the grounding capacitor switching bar to the inverter chassis with a screw.

To change the capacitance to Small, remove the screw that fixes the upper end of the grounding capacitor switching bar and turn the switching bar, as shown in the figure .

(Factory default position)

Warning

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

Prohibited 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, 400V-90kW and 110kW models meet required EMC directive by changing the connection of the grounding capacitor as shown in the figure at the top (changing the capacitance from Small to Large).
