Zero Phase Reactor; Emc Filter - Delta VFD007FP4EA-41 User Manual

Chapter 7 Optional Accessories |CFP2000 Series

7-6 EMC Filter

Following table is the external EMC filter, user can choose corresponding zero phase reactor and suitable
shielded cable length in accord to required noise emission and electromagnetic interference level to have
the best configuration to suppress the electromagnetic interference。
When the application does not consider RE and only needs CE to comply with C2 or C1, there is no need
to install zero phase reactor in input side.

Note 1: To comply with the C1 specifications, an EMC magnetic core needs to be installed on the output side.
Note 2: For frame A~C to comply with EN 61800-3 C1 regulations (when the length of the cable is less than 25m, it
complies with the C1 regulations.), a zero phase reactor has to be installed on the output side, Pass the three
UVW cables through the zero phase reactor. But do not pass the earthing cable and the pig tail of the
insulation through the zero phase reactor.
Note 3: When the length of the cable is longer than 25m, do not install the zero phase reactors listed in the table
below. If the motor cables longer than 25m are connected to a zero phase reactor might cause the
overheating of the iron core inside the zero phase reactor. That will damage the insulation of the cable and
even endanger the life or physical safety of individuals.
Note 4: C2 specifications don't require installing a zero phase reactor.
