Danfoss scroll compressors are designed and
manufactured according to the state of the
art and to valid European and US regulations.
Particular emphasis has been placed on
safety and reliability. Related instructions are
highlighted with the following icons:
This icon indicates instructions to avoid
safety risk.
R
This icon indicates instructions to avoid
reliability risk.
The purpose of this guideline is to help
customers qualify compressors in the unit.
You are strongly advise to follow these
instructions. For any deviation from the
guidelines, please contact Danfoss Technical
Support. In any case, Danfoss accepts no
liability as a result of the improper integration
of the compressor into the unit by the system
manufacturer.

variants
Compressor and
frequency converter
combinations
To have the optimum compressor selection,
select a compressor size which achieves the
peak load system cooling capacity demand at its
maximum speed.
Different frequency converter variants are
available according to:
1. Mains supply voltage
2. IP class (CDS303 drives are available in IP20 or
IP55 housings)
When the compressor size and mains voltage
have been defined in the above selection criteria,
the code number tables from the “Ordering
information and packaging” section provides the
appropriate frequency converter sizes and up
to eight corresponding code numbers for each
compressor model.
Detailed performances can be found in
datasheets and in selection programs.
3. RFI (Radio Frequency Interference) class H2/H3
or HX
4. Printed Circuit Board (PCB) coated or not
coated.
Note this compressor is equipped with
a four poles electrical motor so the applied
frequency from the inverter will be 50 Hz for
25 rps (1500 rpm) up to 200 Hz for 100 rps
(6000 rpm).
