32 Commander S100 User Guide
4.7.2 Internal EMC filter
The Commander S100 is available with C1 and C3 internal filters. It is recommended that the internal EMC filter be kept in place unless there is a
specific reason for disconnecting it. The internal EMC filter reduces radio-frequency emission into the line power supply. The filter may need to be
removed if the ground leakage current is unacceptable. As shown in Figure 4-13, the internal EMC filter is disconnected by removing the screw
❶.
The filter cannot be disconnected in a 200 V drive with a C1 internal filter.
Should the screw need replacing, the screw supplied with the drive is a zinc plated 12 mm M3 Phillips/Slotted screw.

The supply must be disconnected for 5 minutes before disconnecting the internal EMC filter.
