3. Shielded output cables (motor cables) and connect the shield at both ends (motor and
inverter) with a low impedance connection for high frequency. Use PCSx-01 kit supplied
with frame sizes A, B and C inverters. For frame sizes B and C with degree of protection
IP55, use the PCSC-03 shield kit. For frame sizes D and E inverters use the clamps supplied
with the product. Ensure good contact between the cable shield and the clamps. Refer to
Figure 3.4 on page 18 and keep the proper separation from other cables according to
Item 3.2.6 Cable Distances on page 22 . The maximum motor cable length and conduction
and radiated emission levels are presented at Table B.7 on page 168 . Use an external RFI
filter at the input of the inverter if necessary to have a lower emission level and/or a longer
motor cable length. For more information (RFI filter commercial reference, motor cable
length and emission levels) refer to
Table B.7 on page 168 .
4. Shielded control cables and separate the remaining cables according to Item 3.2.6 Cable
Distances on page 22 .
5. Inverter grounding according to the instructions on Item 3.2.4 Grounding Connections on
page 18 .
6. Grounded power supply.
