2.10 SINAMICS G110 Flat Plate Variant

The SINAMICS G110 Flat Plate variant has
been designed to allow greater flexibility in
the installation of the inverter by an advanced
user as an individual unit or as part of an
automation system. Adequate measures
must be taken to ensure the correct heat
dissipation, which may require an additional
external heatsink outside the electrical
cabinet enclosure (see Table 2-3 on page
30).
The installation procedures, both mechanical
and electrical, starting on page 17 of these
Operating Instructions should be performed
unless otherwise stated below. Ensuring that
all warnings and cautions given throughout
the procedures are strictly observed.
WARNING
Operation with the input voltages less than 230 V and 50 Hz or with a pulse
frequency greater than 8 kHz will cause an additional heat load on the inverter.
These factors must be taken into account when designing the installation
conditions and must be verified by a practical load test.
Cooling Considerations
1. For the correct dimensioning of the panel, please consult the panel builder
and his technical documentation.
2. For the correct dimensioning of the external heatsink, please refer to the
technical data as shown in Table 2-1 on page 20.
3. The rear plate must be able to withstand at least 95ºC during fault free
operation and carry the heat load (steel or aluminium plate) under the full
load conditions and the maximum operating temperatures [-10ºC to +50ºC
(14ºF to 122 ºF)]. For further information see Table 2-3 on page 30.
4. The minimum clearance distances of 30 mm at both sides and 100 mm
vertical spacing at both sides must be observed.
5. It is recommended that the mounting area of the rear plate has to be, as a
minimum, at least the same area of the flat plate on the inverter.
6. Side by side or stacked mounting is not allowed for the SINAMICS G110
Flat Plate inverter.
Installation
1. Prepare the mounting surface for the inverter using the dimensions given
in Table 2-1 on page 20.
2. Ensure that any rough edges are removed from the drilled holes.
3. Ensure the inverter's Flat Plate is clean and free from dust and grease.
4. The mounting surface for the Flat Plate and if applicable the external
heatsink must be:
♦ Clean and free from dust and grease.
♦ Smooth.
