4.2.3
EMC-compliant installation
• Shield all cables except for the power supply cable. For the motor cable, you can use
the HD.. option (output choke) instead of the shielding to meet the interference emis-
sion limit values.
• When using shielded motor cables, e.g. prefabricated motor cables from SEW-
EURODRIVE, you must keep the unshielded conductors between the shield and
connection terminal of the inverter as short as possible.
• Connect the shield by the shortest possible route and make sure it is grounded over
a wide area at both ends. If using double-shielded cables, ground the outer shield on
the inverter end and the inner shield at the other end.
• You can also use grounded sheet-metal ducts or metal pipes to shield the cables.
Install the power and control cables separately.
• Provide high frequency compatible grounding for the inverter and all additional units
(wide area metal-on-metal contact between the unit housing and ground, e.g.
unpainted control cabinet mounting panel).
