Attaching ferrite rings to motor and line cables
Where ferrite rings are required, they are included in the scope of supply for the
product.
In the case of PM230 Power Modules of frame sizes FSA to FSC (0.75 kW...15
kW) with integrated Class B filters, attach the
colored ferrite ring to the motor
power cable in order to meet the requirements set out in EMC category C1 for
conducted interference emissions.
Attach the colored ferrite ring between the terminals of the motor power cable
and the shielding plate of the Power Module. Use cables which are shorter than
25 m. Ferrite rings may not be attached to cables measuring more than 25 m
(80 ft) in length.
In the case of PM230 Power Modules of frame size FSB (4 kW...7.5 kW) and frame
size FSC (11 kW ... 15 kW) with integrated Class B filters, the
gray ferrite rings also
have to be attached to the line cable in order to meet the requirements set out in
the EMC guidelines for radiated noise.
