Structure Of The Article Number - Siemens SIMOTICS S-1FG1 Operating Instructions Manual

At installation altitudes of 2000 m above sea level or higher, the voltage stress on the motors
must be reduced accordingly based on the "Factors for reducing the maximum DC-link
voltage" table (reciprocal values from EN 60664-1 Table A. 2).
Table 2- 3
Installation altitude up to m above mean sea level
As the DC-link voltage is reduced, the converter output voltage also decreases.
Operation in a vacuum is not permissible because of the low dielectric strength and poor
heat dissipation.
