The same limits apply to both standards: However, the standards differ with regard to an application
that is extended in the product standard. The user decides which of the two standards applies,
whereby the environmental standard applies in the event of a typical fault remedy.
The main connection between the two standards is explained as follows:

8.3.3 EMC of device
NOTICE
EMC
The drive system can cause high-frequency interference in a living environment that may make interference
suppression measures necessary.
The device is exclusively intended for commercial use. It is therefore not subject to the requirements of the
standard EN 61000-3-2 for radiation of harmonics.
The limit value classes are only achieved if
• the wiring is EMC-compliant
• the length of the shielded motor cable does not exceed the permissible limits

The motor cable shielding must be applied on both sides (frequency inverter shield angle and the
metal motor terminal box). Depending on the inverter version (...-A or ...-O) and according to the type
and use of mains filters or chokes, different permissible motor cable lengths result for compliance with
the declared limit value classes.
Information
Shielded motor cable > 30 m
For connection of shielded motor cables with a length > 30 m, in particular with low power frequency inverters the
current monitoring may trigger, so that use of an output choke (SK CO1-…) is also necessary.
