Technical data
6.8 Electromagnetic compatibility of variable-speed drives
Interference emission - operation in the second environment, Category C4
When connected to IT line supplies, only filtered converters are permissible. Use external
filters without capacitors with respect to ground to limit symmetrical interference emission.

Operation in the First Environment

Interference immunity
You do not have to take any additional measures regarding interference immunity.
Interference emission - operation in the first environment, Category C2
In order that you may operate the drive system in the first environment, Category C2, then in
addition to the requirements for use in the second environment, you must also observe the
limit values related to harmonic currents.
Note
Maintaining the limit values for harmonic currents
With respect to the compliance with limits for harmonic currents, the EMC product standard
EN61800-3 for PDS refers to compliance with standards EN 61000-3-2 and EN 61000-3-12.
Converter with an LO base load power ≤ 1 kW:
It cannot be guaranteed that the limit values are complied with corresponding to IEC 61000-
3-2. The installation person/company or company operating the professionally used device
must obtain authorization from the grid operator to connect the device regarding the
harmonic currents.
Converters with an LO base load input current ≤ 16 A:
These devices are not subject to any limit values, and as a consequence can be connected
to the public low-voltage grid without any prior consultation.
Converters with an LO base load input current > 16 A and ≤ 75 A
The drive system is in compliance with IEC/EN 61000-3-12 under the following
preconditions:
● FSC Power Module, input voltage 3 AC 200 ... 240 V: You use a 3% or 4% line reactor.
● FSD Power Module, input voltage 3 AC 200 ... 240 V: A line reactor is not required
● FSB/FSC Power Module, input voltage 3 AC 380 ... 480 V: You use a 3% or 4% line
reactor.
