Title Functions
•
3-phase AC mains supply to the
frequency converter.
•
The rectifier bridge converts the
AC input to DC current to supply
inverter power.
•
The intermediate DC bus circuit
handles the DC current.
•
Filter the intermediate DC circuit
voltage.
•
Prove mains transient protection.
•
Reduce RMS current.
•
Raise the power factor reflected
back to the line.
•
Reduce harmonics on the AC
input.
•
Stores the DC power.
•
Provides ride-through protection
for short power losses.
•
Converts the DC into a controlled
PWM AC waveform for a
controlled variable output to the
motor.
•
Regulated 3-phase output power
to the motor.
•
Input power, internal processing,
output, and motor current are
monitored to provide efficient
operation and control.
•
User interface and external
commands are monitored and
performed.
•
Status output and control can be
provided.

1.5 Approvals and Certifications

Table 1.2 Approvals and Certifications
More approvals and certifications are available. Contact the
local Danfoss partner. Frequency converters of enclosure
size T7 (525–690 V) are UL certified for only 525–600 V.
The frequency converter complies with UL 508C thermal
memory retention requirements. For more information,
refer to the section Motor Thermal Protection in the
product-specific design guide.
For compliance with the European Agreement concerning
International Carriage of Dangerous Goods by Inland
Waterways (ADN), refer to ADN-compliant Installation in the
product-specific design guide.

1.6 Disposal

Do not dispose of equipment containing
electrical components together with
domestic waste.
Collect it separately in accordance with
local and currently valid legislation.
