2) Grounding capacitor switch
This inverter has a built-in high-attenuation noise filter and is grounded via a capacitor.
A switch makes for easy switching to reduce leakage current from the inverter and the load on the
capacitor. However, be careful, as reducing the load means non-conformity with the EMC standard on
the inverter itself. Always do switching with the power off.
Pressing this switches the grounding capacitor's capacity from small
to large. (Default setting)
Pulling this switches the grounding capacitor's capacity from large to
small. This reduces the leakage current.
When this inverter is connected to the IT system (insulated ground of
power supply or the system has Impedance), the switch has to be
pulled as the figure shows.
