Table 11-7 RFI Filter terminal data

For all the RFI filters, except the size 5 (4200-6115), the power
connections are screw terminals and the ground connections are stud
terminals

11.1.20 Electromagnetic compatibility (EMC)

This is a summary of the EMC performance of the drive. For full details,
refer to the

Unidrive EMC Data Sheet

which can be obtained from the

supplier of the drive.

Immunity

Compliance with immunity standards does not depend on installation
details. drives meet EN50082-2 (generic immunity standard for the
industrial environment) and the following specifications from the
IEC61000-4 group (derived from IEC801):

Part 2  Electrostatic discharge: Level 3
Part 3  Radio frequency field: Level 3
Part 4  Transient burst

Level 4 at the control terminals
Level 3 at the power terminals

Part 5 Surge (at the AC supply terminals)

(as specified by EN50082-2 informative annex):
Level 4 line-to-ground
Level 3 line-to-line

Part 6 Conducted radio frequency: Level 3

Emission

Compliance with emission standards depends on rigorous adherence to
the installation guidelines, including the use of the specified RFI filter in
the AC supply circuit. Compliance also depends on the PWM switching
frequency used in the output stage of the drive, and the length of the
motor cable. For full details, refer to the

Unidrive EMC Data Sheet

which

can be obtained from the supplier of the drive.
When installed according to the instructions the drive can meet the
emission requirements of CENELEC generic emission standards, as
follows:

Table 11-8 Unidrive emission standards

* Compliance with EN50081-1 is restricted to motor cable lengths less
than 100m.
For compliance the optional RFI filter specified below must be used:

Power Drive Systems standard EN61800-3

The drive meets the immunity requirements of EN61800-3 irrespective of
the environment in which it is operating.
The emission requirements of this standard are also met depending on
the environment category, as shown in the table later on this page.

EN61800-3 defines the following:
•

The first environment as one that includes domestic premises. It also
includes establishments directly connected without intermediate
transformers to a low-voltage power supply network which supplies
buildings used for domestic purposes.

•

The second environment is one that includes all establishments
other than those directly connected to a low-voltage power supply
network which supplies buildings used for domestic purposes.

•

Restricted distribution is defined as a mode of sales distribution in
which the manufacturer restricts the supply of equipment to
suppliers, customers or users who separately or jointly have
technical competence in the EMC requirements of the application of
drives.
