INVERTER INTRODUCTION 29
3.7.3 Ground
For safety and to reduce noise, the grounding of the inverter must be well grounded. To avoid electric shocks and
fire accident, the external metal ground wire of the equipment should be short and thick, and should be connected to
specific grounding terminals on the inverter. If several inverters are placed together, all inverters must be connected to
the common ground. Please refer to the following diagrams and ensure that no loop is formed between grounding
terminals.
3.7.4 RFI filter
SC3 series inverters are equipped with built-in RFI filters. These filters are effective in reducing electromagnetic
interference, but to meet CE standard, please refer to section 3.5.4 for installation and wiring.。
