Selecting the power cables
■
General guidelines
Select the input power and motor cables according to local regulations.
•
Current:
Select a cable capable of carrying the maximum load current.
•
Temperature:
For an IEC installation, select a cable rated for at least 70 °C (158 °F)
maximum permissible temperature of conductor in continuous use. For North America,
select a cable rated for at least 75 °C (167 °F).
•
Voltage:
600 V AC cable is accepted for up to 500 V AC. 750 V AC cable is accepted
for up to 600 V AC. 1000 V AC cable is accepted for up to 690 V AC.
To comply with the EMC requirements of the CE mark, use one of the preferred cable types.
See
Preferred power cable types (page 72)
Symmetrical shielded cable reduces electromagnetic emission of the whole drive system
as well as the stress on motor insulation, bearing currents and wear.
Metal conduit reduces electromagnetic emission of the whole drive system.
The protective conductor must always have an adequate conductivity.
Unless local wiring regulations state otherwise, the cross-sectional area of the protective
conductor must agree with the conditions that require automatic disconnection of the supply
required in 411.3.2. of IEC 60364-4-41:2005 and be capable of withstanding the prospective
fault current during the disconnection time of the protective device. The cross-sectional area
of the protective conductor can either be selected from the table below or calculated according
to 543.1 of IEC 60364-5-54.
This table shows the minimum cross-sectional area of the protective conductor related to
the phase conductor size according to IEC/UL 61800-5-1 when the phase conductor and
the protective conductor are made of the same metal. If this is not so, the cross-sectional
