    The Protective Extra Low Voltage (PELV) requirements stated in IEC 61800-5-1 are not fulfilled at altitudes above 2000 m (6562 ft.). For 200V frequency converters the requirements are not fulfilled at altitudes above 5000 m (16 404 ft.). Please contact Danfoss Drives for further information.
  • Page 10 The unit is flexible in its mounting options for as well stand alone mounting and motor mounting. It is also possible to have the unit pre-mounted on a Danfoss Bauer geared motor (3 in one solution). The basic design with a plugable electronic part and a flexible and “spacious” wiring box is extremely servicefriendly and easy to change electronics without the need for unwiring.

    Instead of providing extra cooling, it is possible to reduce the motor load ratio. This can be done by selecting a larger motor. However, the design of the frequency converter puts limits on the size of motors that can be connected to the frequency converter. MG.04.B8.02 - VLT is a registered Danfoss trademark...

  • Page 96: Galvanic Isolation (Pelv)

    PELV isolation of the control card is guaranteed under the following condition: There may be max. 300 V between phase and earth. A motor thermistor connected to terminals 31a-31b must be double isolated to obtain PELV. Danfoss Bauer provides double isolated thermistors. See also the section Diagram in the Design Guide.
