6.8.1.1 Operation in the Second Environment
Interference immunity
You do not have to take any additional measures regarding interference immunity.
Interference emission - operation in the second environment, Category C2
The drive system must comply with the following conditions in order to comply with the limit
values of the second environment, Category C2:
● The drive system is installed by appropriately qualified personnel in compliance with EMC
regulations - and the installation notes provided in the manual.
● You use a shielded motor cable with low capacitance.
● The pulse frequency is not higher than the value set in the factory.
● The drive system is connected to a TN or TT line supply.
● You comply with the permissible motor cable length.
Length of the motor cable (Page 56).
● The converters are equipped with a Category C2 line filter (internal or external).
–
200 V converter frame size FSA … FSC
Converters with integrated filter are suitable for operation in the second environment,
Category C2.
– 200 V converter frame size FSD … FSF
The converters require an external filter, Category C2
– 400 V converter
Converters with integrated filter are suitable for operation in the second environment,
Category C2.
– 690 V converter
Converters of frame sizes FSD and FSE with integrated filter are suitable for operation
in the Second Environment, Category C2.
Converters of frame sizes FSF and FSG with integrated filter are suitable for operation
in the Second Environment, Category C3.
With the external filters, from Section Line filter (Page 125), the converters without
integrated filter comply with the requirements of the Second Environment, Category C2
with reference to interference emission.
If you use converters without integrated filter or a filter other than those mentioned above,
then you are responsible for verifying that the interference emission is limited.
You can use a dedicated radio interference suppression filter for each converter - or a
common filter for several converters.
