1 Remove the front cover and the transparent cover inside
(transparent resin).
For how to remove, refer to [2. 2. 5].
2 Remove the screw for switching of grounding capacitor from
the position of the grounding mark and tighten it to the position
of the grounding mark.
The grounding capacitor's capacity is increased.
3 To recover the shipping state, remove the screw(s) for switching
of grounding capacitor and tighten it/them to the screw hole in
the position of the non-grounding mark.
The grounding capacitor's capacity is reduced.
4 After switching, mount the transparent cover and the front
cover in this order.
For how to mount, refer to [2. 2. 5].
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.
CAUTION
Prohibited
• 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.
