To ensure compliance with UL or IEC 61800-5-1, use the circuit breakers or fuses listed in this chapter. Circuit breakers must be
designed for protection in a circuit capable of supplying a maximum of 10000 A
rms
(symmetrical), 480 V maximum.

3.2.5 EMC-correct Electrical Installation
General points to be observed to ensure EMC-correct electrical installation:
Use only shielded/armored motor cables and shielded/armored control cables.
Ground the shield at both ends.
Avoid installation with twisted shield ends (pigtails), because it reduces the shielding effect at high frequencies. Use the cable
clamps provided.
Ensure the same potential between the drive and the ground potential of PLC.
Use star washers and galvanically conductive installation plates.
