1 SAFETY INSTRUCTIONS
This quick installation guide contains the basic information necessary to commission the CFW300. It has
been written to be used by qualified personnel with suitable training or technical qualification for operating
this type of equipment. The personnel shall follow all the safety instructions described in this manual
defined by the local regulations. Failure to comply with the safety instructions may result in death, serious
injury, and/or equipment damage.
2 SAFETY WARNINGS IN THE MANUAL
NOTE!
It is not the intention of this guide to present all the possibilities for the application of the
CFW300, as well as WEG cannot take any liability for the use of the CFW300 which is not
based on this guide.
For further information about installation, full parameter list and recommendations, visit the
website www.weg.net.
DANGER!
The procedures recommended in this warning have the purpose of protecting the user
against death, serious injuries and considerable material damage.
ATTENTION!
The procedures recommended in this warning have the purpose of avoiding material damage.
NOTE!
The information mentioned in this warning is important for the proper understanding and
good operation of the product.
High voltages are present.
Components sensitive to electrostatic discharge.
Do not touch them.
Mandatory connection to the protective ground (PE).
Connection of the shield to the ground.
3 PRELIMINARY RECOMMENDATIONS
DANGER!
Always disconnect the main power supply before touching any electrical component
associated to the inverter. Several components can remain charged with high voltages or
remain in movement (fans) even after the AC power is disconnected or switched off. Wait at
least ten minutes after turning of f the input power for the complete discharge of the power
capacitors. Always connect the grounding point of the inverter to the protection earth (PE).
The XC10 connector does is not USB compatible, therefore, it cannot be connected to
USB ports.
This connectors ser ve only as interface between the CFW300 frequency inver ter and its
accessories.
NOTE!
Frequency Inverter may inter fere with other electronic equipment. Follow the precautions
recommended in manual available in www.weg.net.
Do not per form any withstand voltage test!
If necessary, contact the manufacturer.
ATTENTION!
Electronic boards have components sensitive to electrostatic discharges.
Do not touch directly on components or connectors. If necessary, first touch the grounding
point of the inverter, which must be connected to the protection earth (PE) or use a proper
grounding strap.
ATTENTION!
When the inverter is stored for a long period, it becomes necessary to per form the capacitor
reforming. Refer to the procedure recommended in www.weg.net.
4 ABOUT THE CFW300
The CF W300 frequency inverter is a high-performance product which allows speed and torque control of

6 RECEIVING AND STORAGE
The CF W300 is supplied packed in a cardboard box. There is an identification label affixed to the outside
of the package, identical to the one affixed to the side of the inverter.
Verify whether:
The CF W300 identification label corresponds to the purchased model.
Any damage occurred during transportation.
Report any damage immediately to the carrier.
If the CF W300 is not installed soon, store it in a clean and dry location (temperature between -25 ºC and
60 ºC (-13 ºF and 140 ºF)), with a cover to prevent dust accumulation inside it.

9 INSTALLATION AND CONNECTION
Environmental Conditions
Avoid:
Direct exposure to sunlight, rain, high humidity or sea-air.
Inflammable or corrosive gases or liquids.
Excessive vibration.
Dust, metallic particles or oil mist.
Environment conditions permitted for the operation of the inverter:
Temperature surrounding the inverter: 0 ºC to 50 ºC ( 32 ºF to 122 ºF) – IP20.
For temperatures surrounding the inver ter higher than the specifications above, it is necessar y to apply
of 2 % of current derating for each degree Celsius, limited to an increase of 10 ºC (50 ºF).
Air relative humidity: 5 % to 95 % non-condensing.
Maximum altitude: up to 1000 m (3.300 ft) - rated conditions.

10.2 INSTALLATIONS ACCORDING TO EUROPEAN DIRECTIVE OF ELECTROMAGNETIC
COMPATIBILITY
The CF W300 inverter series, when properly installed, meet the requirements of the directive of the
electromagnetic compatibility.
These inverters were developed for professional applications only. Therefore, the emission limits of
harmonic currents by the standards EN 61000-3-2 and EN 61000-3-2/A 14.
10 . 2 .1 Conformal Installation
1. Shielded output cables (motor cables) with shield connected at both ends, motor and inverter, by meanse
of a low impedance to high frequency connection. Maximum motor cable length and conduced and
radiated emission levels according to Table 6.
2. Shielded control cables, keeping the separation distance from other cables according to Table 3.2 the
user's manual.
3. Grounding of the inver ter according to instruction of the 3.2.4 Grounding Connections the user's manual.
4. Grounded power supply.
5. Use short wiring to ground the external filter or inver ter.
6. Ground the mounting plate using a flexible braid as short as possible. Flat conductors have lower
impedance at high frequencies.
7. Use sleeves for cable conduits whenever possible.
The CF W300 is suitable for application in a circuit able to supply not more than 30.000 symetric Arms
maximum of 127 / 240 V, when protected by fuses classified as indicated below:

DANGER!
The inverter must be connected to a protective ground (PE).
Use a minimum wire gauge for ground connection equal to the indicated in Table 3.
Connect the inverter grounding connections to a ground bus bar, to a single ground point
or to a common grounding point (impedance ≤ 10 Ω).
The neuter conductor of the line that feeds the inverter must be solidly grounded; however
this conductor must not be used to ground the inverter.
Do not share the grounding wiring with other equipment that operate with high currents
(e.g.: high voltage motors, welding machines, etc.).
NOTE!
The wire gauges listed in Table 3 are guiding values. Installation conditions and the maximum
permitted voltage drop must be considered for the proper wiring sizing.

10.3.2 Characteristics of the RFI Filter
CFW300 inverters are installed with external filter when it is intended to reduce the disturbance conducted
from the inverter to the power line in the high frequency band (> 150). It is obser ve the maximum levels of
conducted emission of electromagnetic compatibility standards, such as EN 61800-3 and EN 55011.

The accessories are hardware resources that can be added in the application with the CFW300.
The accessories are incorporated to the inverters in an easy and quick way by using the concept “Plug and
Play”. The accessor y must be installed or modified with the inverter de-energized. They may be ordered
separately, and are sent in their own package containing the components and manuals with detailed
instructions for their installation, operation and setting.

12 START-UP PREPARATION
DANGER!
Always disconnect the main power supply before making any connection.
1. Check if the power, grounding and control connections are correct and firm.
2. Remove all the materials left behind from the installation work from inside the inverter or the cabinet.
3. Verif y the motor connections and if its voltage and current are within the inverter rated value.
4. Mechanically uncouple the motor from the load. If the motor cannot be uncoupled, make sure that any
speed direction (for ward or reverse) will not result in personnel injur y and/or equipment damage.
5. Close the inverter or cabinet covers.
6. Measure the power supply and verify if it is within the allowed range.
7. Apply power to the input: close the input disconnecting switch.
8. Check the result of the first time power-up:
