FC 300 Operating Instructions

Motor Cables

See chapter General Specifications for correct dimensioning of motor cable cross-section and length.
Use a screened/armoured motor cable to comply with EMC emission specifications
•
unless otherwise stated for the RFI filter used.
Keep the motor cable as short as possible to reduce the noise level and leakage currents.
•
Connect the motor cable screen to the decoupling plate of the FC 300 and to the metal cabinet of the motor.
•
• Make the screen connections with the largest possible surface area (cable clamp). This is
done by using the supplied installation devices in the FC 300.
Avoid mounting with twisted screen ends (pigtails), which will spoil high frequency screening effects.
•
If it is necessary to split the screen to install a motor isolator or motor relay, the screen must
•
be continued with the lowest possible high frequency impedance.
