Leakage Current Of The Emc Filter - Fuji Electric FRENIC-HVAC Manual

Clamp for control
signal lines
5) When using an externally connected EMC filter (optional), place the inverter and filter on a grounded metal
plate such as the surface of a panel, as shown in Figure 8.3. If noise emissions exceed the standard, place
the inverter and any peripheral equipment inside a metal panel. For more information about how to use the
inverter in combination with a filter, see Table 8.4.

8.3.3 Leakage current of the EMC filter

This product uses grounding capacitors for noise suppression which increase the leakage current. Check
whether there is no problem with electrical systems. When using an EMC filter, the leakage current listed in
Table 8.4 is added. Before adding the filter, consider whether the additional leakage current is allowable in the
context of the overall system design.
