4. POWER CABLING
1. A power cable for a fixed installation. A cable for the specified mains voltage. A shielded cable is not necessary. We recom-
mend an MCMK cable.
2. A symmetrical power cable with a concentric protection wire. A cable for the specified mains voltage. We recommend an
MCMK cable. See Fig. 22.
3. A symmetrical power cable with a compact low-impedance shield. A cable for the specified mains voltage. We recommend
an MCCMK, or an EMCMK cable. We recommend that the cable transfer impedance (1...30MHz) is a maximum of 100 mΩ/m.
See Fig. 22.
* For the EMC level C2, it is necessary to have a 360º earthing of the shield with cable glands in the motor end.
4. A screened cable with a compact low-impedance shield, for example a JAMAK, or an SAB/ÖZCuY-O cable.

In all the frames, to obey the EMC requirements, use the default values of the switching frequencies.
If you installed a safety switch, make sure that the EMC protection continues from the start of the cables until their ends.
4.2 UL STANDARDS ON CABLING
To obey the UL (Underwriters Laboratories) regulations, use a UL-approved Class 1 copper wire with a minimum heat resistance
of 60 or 75 °C (140 or 167 °F).
You can use the drive on a circuit that gives a maximum of 100 000 rms symmetrical amperes, and a maximum of 600 V, when
the drive is protected by Class T and J fuses.
4.3 CABLE DIMENSIONING AND SELECTION
These instructions are valid only for processes that have 1 motor and 1 cable connection from the AC drive to the motor. In
other conditions, speak to the manufacturer to get more information.
