NOTES!
NOTES:
1) For EDX-150-21-E – N4S and EDX-220-21-E-N4S models, additional items will be found
inside the outer packaging including 2pc of EMC conformed waterproof (IP65) ferrite core.
2) If application requires meeting published EMC performance class, you must fit the ferrite
cores onto the motor cable outside the plastic sheath as shown in the above diagram. The
quadrilateral type ferrite core should be fitted as close as possible to inverter output terminals
T1, T2, T3, and the circular type ferrite core should be fitted close to the motor.
Please also note that the length of the motor cable CANNOT exceed 5 metres if the declared
EMC performance is to be met.
