EMC emission standards -
compliance information
Conditions for EMC compliance
The installer of the drive is responsible for ensuring compliance
with the EMC regulations that apply where the drive is to be used.
The drive will comply with the standards for emission, such as
EN50081-2, only when the instructions given in this section are
adhered to closely.
Special note for EN61800-3 (EMC Power Drive Systems)
For installation in the ‘second environment’, i.e. where the low
voltage supply network does not supply domestic premises, and
where the rated input current of the drive system exceeds 100A, no
filter is required in order to meet IEC61800-3 (EN61800-3).
Operating the drive in this environment without an EMC filter may
cause interference to nearby electronic equipment whose
sensitivity has not been appreciated. The user must take remedial
measures if this situation arises.
If the consequences of unexpected disturbances are severe, it is
recommended that the emission limits of EN50081-2 be adhered to.
In any other case, adhere to the precautions described in this
section.
When the drive is used in the ‘first environment’, i.e. where the low
voltage supply network also supplies domestic premises, the following
warning applies:
This is a product of restricted distribution class
according to IEC61800-3. In a domestic environment this
product may cause radio interference in which case the
user may be required to take adequate measures.

EMC emission standards -
instructions
Follow these instructions in addition to those given earlier in this chapter.
Enclosure
The enclosure must be made of metal but does not require special EMC
features.
Back-plate
Ensure the enclosure back-plate is unpainted, but it may be zinc plated.
Mounting brackets electrically connected to the back-plate
Ensure the mounting brackets for the drive and RFI filter make direct
electrical connection with the back-plate.
Grounding
For compliance with EMC emission standards, employ the grounding
arrangements shown in this section. These arrangements are in addition
to (not instead of) the safety requirements.
The fitting of an additional safety ground will not reduce the EMC
performance.
External braking resistor
When an external braking resistor is to be mounted outside the
enclosure, ensure the following:
•
The resistor housing will give electromagnetic shielding (without
compromising ventilation)
•
The braking-resistor wiring must be shielded/armoured
Installing an RFI filter
For compliance with emission standards such as EN 50081-1 or
EN 50081-2, use an RFI filter for each drive, as shown in Table 2-11 .
(Standards that are met are specified in Appendix B Data on page 26.)

RFI filter details
Make a note of the following for each RFI filter to be used:
•
Part number
•
Maximum power dissipation figure
•
IP rating
Dimensions of the bookcase RFI filter
Dimensions of the footprint RFI filter
The filter has a high leakage current to ground. A
permanent fixed ground connection must be provided.
