Cable connection
Separate the control cables from the power cables as much as possible.
Keep the connecting cables away from rotating mechanical parts.
EMC-compliant installation of external line filter options
All 400 V converters must be mounted in a cabinet with a special EMC gasket around the
door.
All the following ferrite cores are recommended in accordance with EN 55011.
For 400 V unfiltered frame size B converters fitted with the filters specified in Section B.1.7:
To meet the radiated and conducted emissions Class A, attach 1 x ferrite core of Type "
WeiAiPu V18004", or equivalent in the vicinity of the motor output terminals (U, V, and W,
excluding the PE terminal) of the converter.
For 400 V unfiltered frame size C converters fitted with the filters specified in Section B.1.7:
To meet the radiated and conducted emissions Class A, attach 1 x ferrite core of Type
"Wurth 742-715-4", or equivalent in the vicinity of the converter mains terminals.
For 400 V unfiltered frame size D converters fitted with the filters specified in Section B.1.7:
To meet the radiated and conducted emissions Class A, attach 2 x ferrite cores of Type
"Wurth 742-715-5" or equivalent in the vicinity of the converter mains terminals; attach 1x
ferrite core of Type "Wurth 742-712-21" or equivalent in the vicinity of the external line filter
mains terminals.
For 400 V unfiltered frame size E converters fitted with the filters specified in Section B.1.7:
To meet the radiated and conducted emissions Class A, attach 1 x ferrite core of Type
"Seiwa E04SRM563218" or equivalent in the vicinity of the converter mains terminals; attach
2 x ferrite cores of Type "Seiwa E04SRM563218" or equivalent in the vicinity of the motor
terminals of the converter.
For 230 V filtered frame size AA/AB converters:
To meet the radiated and conducted emissions Class B, attach 1 x ferrite core of Type "K3
NF-110-A(N)GY0", or equivalent in the vicinity of the motor output terminals (U, V, and W,
excluding the PE terminal) of the converter; attach 1x ferrite core of Type "K3 NF-110-
A(N)GY0" or equivalent on the motor cable outside the threaded hole of the cabinet; attach 2
x ferrite cores of Type "K3 NF-110-A(N)GY0" or equivalent on the motor cable in the vicinity
of the motor.
