1.4.3 Grounding capacitor switching method
The inverter is grounded through a capacitor. The leakage current from the inverter can be reduced using the selector
switch, switching bar or switching screw (depending on the model) on the main circuit terminal board. This switching
device is used to detach the capacitor from the grounding circuit or to reduce its capacitance.
Some models have capacitors that can be detached completely, while others have capacitors whose capacitances
can be reduced.
Note 1: Please note that, without the capacitor, the inverter does not comply with the EMC directive.
Note 2: When attaching or detaching the capacitor, be sure to turn off power.
