UL standards on cabling
To meet the UL (Underwriters Laboratories) regulations, use a UL-approved copper cable with
a minimum heat-resistance of +60/75°C. Use Class 1 wire only.
The units are suitable for use on a circuit capable of delivering not more than 100,000 rms sym-
metrical amperes, 600V maximum.
4.1.1
Cable dimensioning and selection
Table 14 shows the minimum dimensions of the Cu/Al-cables and the corresponding fuse siz-
es. Recommended fuse types are gG/gL.
These instructions apply only to cases with one motor and one cable connection from the drive
to the motor. In any other case, ask the factory for more information.
