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 and
suitable for the prospective short-circuit current provided by the supply
network. The method of installation and ambient temperature affect the cable
current carrying capacity. Obey local regulations and laws.
•
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).
Important: For certain product types or option configurations higher
temperature rating may be required. See the technical data for details.
•
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 68)
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.
