Derating factors
For installation altitudes above 2000 m above sea level, reduce the voltage stress of the
motors according to table "Factors to reduce the maximum DC link voltage" (reciprocal
values from EN 60664-1 Table A. 2).
Table 2- 7
Reducing the DC link voltage reduces the converter output voltage. The operating range in
the F-v diagram is thus also reduced.
You can find the F-v diagrams in the associated data sheet.
Operation in a vacuum is not permissible due to the low voltage strength and the poor
cooling.

Selection and ordering data
2.5.1
Order designation
The article number is used as the order designation. The article number consists of a
combination of letters and numerals. When placing an order, it is sufficient just to specify the
unique article number.
The article number consists of three blocks that are separated by hyphens. The first block
incorporates seven characters and designates the product family and size of the primary or
secondary section. Additional design features are encrypted in the second block, such as
length and velocity. The third block is provided for additional data.
Please note that not every theoretical combination is possible.
