Mounting a SINAMICS V20 Flat Plate variant
The SINAMICS V20 Flat Plate variant is designed to allow greater flexibility in the installation
of the converter. Adequate measures must be taken to ensure the correct heat dissipation,
which may require an additional external heatsink outside the electrical enclosure.
WARNING
Additional heat load
Operation with an input voltage greater than 400 V and 50 Hz or with a pulse frequency
greater than 4 kHz will cause an additional heat load on the converter. These factors must
be taken into account when designing the installation conditions and must be verified by a
practical load test.
CAUTION
Cooling considerations
The minimum vertical clearance of 100 mm above and below the converter must be
observed. Stacked mounting is not allowed for the SINAMICS V20 converters.
