Those manuals are available on WEG website - www.weg.net.
2.2 TERMS AND DEFINITIONS USED IN THE MANUAL
Regenerative Frequency Converter: three-phase switched boost-type converter that converts alternating voltage
(AC) of the grid into DC voltage (DC Link). It can absorb energy from the grid (AC) or return energy to it, being used
as a DC voltage supply that feeds one or more output inverters.

frequency converter. It controls the motor.
Normal Duty (ND): Normal Duty (ND); operating duty of the converter that defines the maximum current values

2.3 ABOUT THE CFW-11M G2 RB AND CFW-11W G2 RB
The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters are the second generation of the
CFW-11M RB and CFW-11W RB regenerative frequency converter line respectively. The main differences in relation
to the previous generation are the following:
Smaller. The CFW-11M G2 RB is shorter and slimmer than the CFW-11M RB, allowing the installation of three
UP11 G2 RB in a panel with columns 800 mm wide and 2000 mm high. The CFW-11W G2 RB is shorter, slimmer
and less deep than the CFW-11W RB, allowing the installation of three UP11W G2 in a panel with columns 800
mm wide, 2000 mm high and 600 mm deep.
More modern. State-of-the-art components have increased the power of the converters.
The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters are high-performance products
that enable the rectification of three-phase lines with the following advantages:
Low harmonic distortion in the input current.
Capacity to return energy to the line (regeneration), enabling high braking torques.
The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters have a modular design, with
configurations containing one to five power units (UP11 G2 or UP11W G2), one control unit (UC11RB G2) and
wiring cables. The modular assembly increases the converter reliability and simplifies its maintenance. There is a
single control unit (UC11RB G2) which can control up to five UP11s G2 or five UP11Ws G2.
CFW-11MW G2 RB | 2-3
General Information
The CFW-11W G2 RB regenerative frequency converter line is water cooled, being smaller than the other converters.
The UP11s, UP11Ws and UC11RB G2 are fed through an external +24 Vdc power supply. Figure 2.1 on page 2-4 and
Figure 2.3 on page 2-6 respectively show the general diagrams of the air-cooled and water-cooled converters,
considering the configuration with three UP11s connected in parallel.
The UC11RB G2 control unit controls the power units. The control unit contains the control rack of the CFW-11
2
line and the ICUP board. This board sends signals to all UP11 G2 or UP11W G2 (PWM, control signals, etc.), and
receives signals from them (current, voltage feedback, etc.).

NOTE!
To assemble the complete drive, several additional items are necessary, such as fuses on the DC
power supply of each UP11 or UP11W power unit, external pre-charge circuit and input filters.
NOTE!
It is not necessary to include a current transformer (CT) in the drive for short-circuit protection at the
output against the ground, since each UP11 and UP11W has its own internal protection.

3 INSTALLATION AND CONNECTION
This chapter describes the procedures for the electrical and mechanical installation of the CFW-11M and
CFW-11W G2 RB. The directions and suggestions must be observed to ensure the safety of people and
equipment and the proper operation of the inverter.
3.1 AIR-COOLED UP11 G2 MECHANICAL INSTALLATION
The power units must be installed in the drive panel appropriately, allowing easy extraction and reinstallation in
case of maintenance. The mounting must be such to avoid damage during the panel transportation.
3.1.1 Environmental Conditions
Avoid:
Direct exposure to sunlight, rain, excessive moisture or marine environment.
Inflammable or corrosive liquids or gases.
Excessive vibration.
Dust, metal particles or oil suspended in the air.
Permissible environment conditions for operation:
Ambient temperature: 0 °C to 45 °C (32 ºF to 113 ºF) - rated conditions (measured around the inverter). From
45 ºC to 55 ºC (113 ºF to 131 ºF) - 2 % of current derating for each Celsius degree above 45 ºC (113 ºF).
Maximum altitude: up to 1000 m (3.300 ft) – rated conditions.
From 1000 m to 4000 m (3.300 ft to 13.200 ft) – 1 % of current derating for each 100 m (330 ft) above 1000 m
(3.300 ft) of altitude.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) - maximum voltage (480 V for models 380...480 V and 690 V for
models 500...690 V) derating of 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
3
Maximum altitude of 4000 m (13.200 ft).
Air relative humidity: 5 % to 95 % non-condensing.
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation must
not cause conduction of the accumulated residues.
3.1.2 Part List
For the panel mounting of the CFW11M G2 RB, it is necessary: UC11RB G2 control set, UP11 G2 power units,
synchronism transformers and cable set to connect the UC11RB G2 to the UP11 G2. Table 3.1 on page 3-1,

3.1.4 Panel Ventilation
The efficiency of the panel ventilation depends on the equipment installed inside the panel, such as fans, air inlets
and filters. The internal fan of the UP11 G2 is not enough to cool the entire panel.
