EMC filter compatibility
The drive has an internal EMC filter (+E210) as standard. However, for the UL (NEC) drive
types, the filter is disconnected as default. The filter is typically not needed in North American
installations. If you are concerned with EMC issues, and install the drive to a symmetrically
grounded TN-S system, IT system, corner-grounded delta or mid-point-grounded delta
system, you can connect the internal EMC filter. See section
.
Note:
When the internal EMC filter is disconnected, the electromagnetic compatibility of the
drive is reduced.
■
Ground-to-phase varistor compatibility
The drive is equipped with an internal ground-to-phase varistor as standard. However, for
the UL (NEC) drive types, the ground-to-phase varistor is disconnected as default.
For connecting the ground-to-phase varistor, see section
ground-to-phase varistor – North America (page 231)
