 200V/55kW models and larger 400V/90kW, 110kW models: Grounding capacitor switching bar
1
Prohibited
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 switching screw
«132kW, 160kW»
Prohibited
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.

In case of one phase grounding system (A three-phase supply power is connected in delta),
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.

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