1. For type of fuse, see section Fuses.
2. American Wire Gauge.
3. Measured using 30 m screened motor cables at rated load and rated frequency.
4. Min. cable cross-section is the smallest cable cross-section allowed to be fitted on the terminals. Max. cable cross
section is the maximum possible cable cross section that can be fitted on the terminals.
Always comply with national and local regulations on min. cable cross-section.
5. Aluminium cables with cross-section above 35 mm
2
must be connected by use of an Al-Cu connector.
■ Fuses
Non UL compliance
If UL/cUL is not to be complied with, we recommend the above mentioned fuses or:
VLT 7002-7072 380-460 V type gG
Not following the recommendation may result
in unnecessary damage of the drive in case of
malfunction. Fuses must be designed for protection in
a circuit capable of supplying a maximum of 100000
A
rms
(symmetrical), 500 V/600 V maximum.
