200V/55kW models and larger 400V/90kW, 110kW models: Grounding capacitor switching bar
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 .

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, 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).

400V/132kW models and larger: Grounding capacitor screw
«132kW, 160kW»
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.
