ABOUT THIS GUIDE

This guide shows how to install and how to start-up in V/f mode the
CFW-11 inverter models from frame size A to G.
For detailed information please refer to the CFW-11 user's manual
and programming manual.
It is also possible to operate the CFW-11 in the following control
modes: VVW, Sensorless Vector Control and Vector Control with
Encoder, for induction motors and Sensorless and Encoder Vector
Control for Permanent Magnet (PM) machines. Please see the
programming manual.
For information on other functions, accessories and communication,
please see the WEG website www.weg.net

SAFETY INSTRUCTIONS

Fully read this guide before installing or operating the inverter.
Only trained and qualified personnel should attempt to install,
start-up, and troubleshoot this type of equipment. The personnel
must follow all the safety instructions described in this guide and/
or defined by the local regulations.
DANGER!
Failure to comply with the safety instructions may
result in death, serious injury, and equipment damage.
Always disconnect the main power supply before
touching any electrical device associated to the
inverter.
Several components can remain charged with high
voltage and/or in movement (fans), even after the AC
power supply has been disconnected or switched off.
Wait at least 10 minutes to assure the total discharge
of the capacitors.
Always connect the equipment frame to the protection
earth (PE).
DANGER!
Crushing Hazard
In order to ensure safety in load lifting applications,
electric and/or mechanical devices must be installed
outside the inverter for protection against accidental
fall of load.
DANGER!
This product was not designed to be used as a safety
element. Additional measures must be taken so as to
avoid material and personal damages.
The product was manufactured under strict quality
control, however, if installed in systems where its
failure causes risks of material or personal damages,
additional external safety devices must ensure a safety
condition in case of a product failure, preventing
accidents.
NOTE!
For the purpose of this guide, qualified personnel are
those trained and able to:
1. Install, ground, power-up, and operate the CFW-11
according to this guide and to the current legal
safety procedures.
2. Use the protection equipment according to the
established regulations.
3. Provide first aid.

CFW-11 MAIN DESCRIPTION

The CFW-11 frequency inverter is a high performance product with
models covering the range from 1 to 600 HP (0.75 to 450 kW) in seven
different mechanical sizes and line voltages from 200 V to 480 V. It
is designed for speed and torque control of three-phase induction
motors and PM motors. The main characteristic of this product is
the "Vectrue" technology, with the following control modes: Scalar
control (V/f), V V W, "Sensorless vector control" and "Vector control
for manual downloads.
with encoder". Additional highlight functions and features: "Optimal
Braking", "Self-Tuning" and "Optimal Flux".
For more detailed information refer to the CFW-11 user's manual and
the programming manual.

RECEIVING AND STORAGE

When receiving the product verify if:
The CFW-11 nameplate data matches the purchase order. See
models and technical characteristic in
Any damage occured during transportation. If any problem is
detected, contact the carrier immediately.
If the CFW-11 is not to be installed immediately, store it within its
original cardboard box in a clean and dry room (storage temperatures
between -25 °C (-13 °F) and 60 °C (140 °F).

MECHANICAL INSTALLATION

ENVIRONMENT
Avoid:
ƒ
Direct exposure to sunlight, rain, high humidity, or sea-air.
ƒ
Inflammable or corrosive gases or liquids.

GENERAL MOUNTING CONSIDERATIONS

Consult the inverter weight in
Mount the inverter in the upright position on a flat and vertical surface.
External dimensions and fixing holes position according to the
figure
Minimum mounting clearances requirements for proper cooling air
circulation are specified in
Note:
ƒ
For sizes A, B, and C: side-by-side mounting - no clearance
required between inverters if top cover is removed.
Do not install heat sensitive components right above the inverter.
