The main machine power driving parameters are shown in the machine rating plate. For more
information, contact Danfoss representative.
You can connect one of the temperature signals (from the low voltage connector) to the temperature
surveillance pin in the inverter and make sure that the inverter has the machine temperature protection
feature activated.
Supporting structure requirements
Do not install the electric machine near or in direct contact with easily flammable materials.
The surface of the electric machine can be hot.
The mating housing arrangement of the electric machine must be secure and sufficiently rigid to prevent
vibrations and mechanical failures. Necessary actions should be taken to avoid corrosion on the mating
housing arrangement.
The supporting structure for the electric machine must be such that the electric machine can be
mounted using its allowed mounting positions, see Chapter
The mounting space must be adequate for the electric machine mounting and possible auxiliary
components. See the length and the diameter data of the electric machine from the product drawing.
Main dimensions of the electric machine are shown in the Figure below (the illustration may differ from
the actual electric machine).
The electric machine has a SAE 3 D-end flange (IM 3001). A SAE 3 flywheel housing is required as mating
flange. The machine's N-end flange (SAE 4 flywheel housing) can be used for auxiliary components or
support.
Allowed mounting
positions.
