.
A power cable for a fixed installation. A cable for the specified mains voltage. A shielded
cable is not necessary. We recommend 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. 36.
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. 36. * = For the EMC level C2, it is necessary to have a 360º grounding of the
shield with cable glands in the motor end.

.
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.

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.
5.3
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.
5.3.1
CABLE AND FUSE SIZES
We recommend the fuse type gG/gL (IEC 60269-1). To make a selection of the fuse voltage
rating, refer to the mains. Do not use larger fuses than what is recommended in Table 16 and
Table 17.
