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 follows:
First environment: Restricted distribution only: specified RFI filter
required
Second environment: No RFI filter required (but RFI filter(s) are
recommended where sensitive electronic systems are operating
nearby); emission limits are
under consideration
EN61800–3 defines 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.
Note
If a Power Drive System is included as part of equipment
covered by a separate EMC product standard, the EMC
standard for the complete equipment applies.
