Table 2 – CF01F and CF02F Inverter specification
Note 1 – Voltage range approved by Agencies.
Note 2 – Operating below the nominal input voltage may reduce the compressor cooling capacity due to lower
link voltage and/or due to Inverter power limitation.
Note 3 – Minimum voltage without impact on compressor starting performance. The compressor may start with
voltages below this limit if starting conditions (suction and discharge pressures) are not extremes.
Note 4 - Maximum voltage without impact on performance and long term reliability.
Note 5 – Maximum transient voltage without the Inverter being damaged, but with impact on performance, and if
it is continuously supplied at this voltage level, there may be a possible impact on product lifespan.
Note 6 – Voltages above this limit may damage the product.
Note 7 – The maximum input power may be reduced depending on the input voltage, ambient temperature, and
compressor speed.
Note 8 – For frequency and serial communications, the standby consumption is presented as
sleep mode /
standby
. The lower standby consumption (sleep mode) is activated in Frequency and Serial control after the
command to turn off the compressor. To stay in sleep mode, it is necessary to stop sending commands after the
compressor stops. Any transition level in the communication connector will wake up the Inverter.
Note 9 – Inrush current refers to a transient phenomenon that occurs when the power supply cord is connected
to the power grid or in the case of returning after power outages. The CF01F and CF02F Inverters are designed
accordingly and can reliably withstand this current along with the expected product lifespan. Excessive inrush
current events may damage the Inverter. Embraco recommends having the appliance supply cord directly
connected to Inverter power input without any disconnection means regarding Inverter installation. The CF01F
and CF02F Inverters shall not be de-energized on every compressor turn off. Please, get in contact with your
Nidec GA Application Engineer for any assistance or application assessment needed.
Note 10 – The output frequency and the motor speed may have a reduced range based on the respective
compressor's maximum working conditions.
Note 11 – The motor speed range of compressors may change depending on the model. The speed range of
Compressors is specified on its datasheet.
Note 12 – Inverter shall be stored in a proper environment to avoid condensation and oxidation of its parts.
Note 13 – If extended storage and operating temperatures are required, please get in contact with your Nidec GA
Application Engineer.
Note 14 – Agency approval temperature.
Note 15 – The measuring point of Inverter ambient temperature is 50 mm far from the Inverter label side, as
shown in Figure 1.
Note 16 – The maximum ambient temperature around the Inverter depends on the input power, as shown in the
Table 3. This limit shall be observed during the refrigerator's heating test.
