2) Grounding capacitor switch
Single-phase 240V model and three-phase 500V model have 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.
Note1) In case of three phase 500V-4.0kW model, if you disconnect the capacitor from ground, set the
parameter of carrier frequency
f300 to 4kHz or less with motor cable length 30m or less.
Note2) Don’t disconnect the grounding capacitor with the switch, if you set the overload characteristic
selection
aulto 2.
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.
