Disabling the Built-in EMC Filter
0.4-22kW
Before using the inverter, confirm the power supply’s grounding system. Disable the EMC
filter if the power source has an asymmetrical grounding connection. Refer to the figures
below to locate the EMC filter on/off terminal and replace the metal bolt with the plastic bolt.
If the EMC filter is required in the future, reverse the steps and replace the plastic bolt with
the metal bolt to reconnect the EMC filter.
