Note Special feature of FSG inverters FSG inverters with integrated C3 line filter can be operated in IT line systems if you remove the screw for functional grounding. Figure 4-2 Remove screw for functional grounding (Page 50) If you remove the screw for functional grounding, the EMC properties deteriorate and the requirements of Class C3 are no longer met. ● Inverter without line filter: – Operation on all IT line systems permissible. The devices which have been sourced have Internal filters which cannot be disconnected as with Frame Size G devices. Therefore without the ground reference the filters will fail. Tractor
