4.6 Ground leakage
The ground leakage current depends upon whether the internal EMC filter is connected or not. The drive is supplied with the filter connected.
Instructions for disconnecting the internal filter are given in section 4.7.2 Internal EMC filter .
Table 4-10 Ground leakage and touch current value
The above leakage currents do not take into account any leakage currents of the motor or motor cable. Find additional details on the ground leakage
in the Commander S100 EMC data-sheet.
4.6.1 Use of a residual current device (RCD)
Only type B RCDs should be used with this product.
If an external EMC filter is used with an ELCB / RCD, a delay of at least 50 ms should be incorporated to ensure spurious trips are not seen. The
leakage current is likely to exceed the trip level if all of the phases are not energized simultaneously.

When the internal filter is installed the leakage current is high. In this case, a permanent fixed ground connection must be provided, or
other suitable measures taken to prevent a safety hazard occurring if the connection is lost.
When the touch current exceeds 3.5 mA, a permanent fixed ground connection must be provided using two independent conductors each
with a cross-section equal to or exceeding that of the supply conductors. The drive is provided with two ground connections to facilitate
this. Both ground connections are necessary to meet EN 61800- 5-1: 2007.
