Quick Installation Guide
CFW100 Micro Drive
1 SAFETY INSTRUCTIONS
This quick installation guide contains the basic information necessary to commission the CFW100. 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
CFW100, as well as WEG cannot take any liability for the use of the CFW100 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 off the input power for the complete discharge of the power
capacitors. Always connect the grounding point of the inverter to the protection earth (PE).
Connectors XCA and XCB do not present USB compatibility; therefore, they cannot be
connected to USB doors.
These connectors serve only as interface between the CFW100 frequency inverter and
its accessories.
NOTE!
Frequency Inverter may interfere with other electronic equipment. Follow the precautions
recommended in manual available in www.weg.net.
Do not perform 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 perform the capacitor
reforming. Refer to the procedure recommended in www.weg.net.
4 ABOUT THE CFW100
The CFW100 frequency inverter is a high-performance product which allows speed and torque
control of three-phase induction motors. This product provides the user with the options of vector
(VVW) or scalar (V/f) control, both programmable according to the application.

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 inverter higher than the specifications above, it is necessary 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.
From 1000 m to 4000 m (3.300 ft to 13.200 ft) – 1 % of current derating for each 100 m above 1000 m
of altitude.
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation
must not originate conduction through the accumulated residues.

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 2.
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 2 are guiding values. Installation conditions and the maximum
permitted voltage drop must be considered for the proper wiring sizing.

For the correct connection of the control, use:
1. Gauge of the cables: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum torque: 0.5 N.m (4.50 lbf.in).
3. Wiring of the connector of the control board with shielded cable and separated from the other wiring
(power, command in 110 V / 220 Vac, etc.)
10.3 INSTALLATIONS ACCORDING TO EUROPEAN DIRECTIVE OF ELECTROMAGNETIC
COMPATIBILITY
The CFW100 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.
10.3.1 Conformal Installation
1. Shielded output cables (motor cables) with shield connected at both ends, motor and inverter, by means
of a low impedance to high frequency connection. Maximum motor cable length and conduced and
radiated emission levels according to Table 5. For more information (RFI filter commercial reference,
motor cable length and emission levels) refer to the Table 5.
2. Shielded control cables, keeping the separation distance from other cables according to Table 3.2 the
user's manual.
3. Grounding of the inverter according to instruction of the 3.2.4 Grounding Connections the user's manual.
4. Grounded power supply.
5. The inverter and external filter must be mounted on a common metal plate.
6. The wiring between filter and inverter must be as short as possible.
7. The grounding must be done according to recommendation of the CFW100 user's manual.
8. Use short wiring to ground the external filter or inverter.
9. Ground the mounting plate using a flexible braid as short as possible. Flat conductors have lower
impedance at high frequencies.
10. Use sleeves for cable conduits whenever possible.

Category C3: inverters with a voltage rating less than 1000 V and intended for use in the Second
Environment only (not designed for use in the First Environment).
10.3.3 Characteristics of the RFI Filter
The CFW100 inverters, when installed with external filter, are used to reduce the conducted from the
inverter to the power line in the high frequency band (>150). It is necessary to meet the maximum levels of
conducted emission of electromagnetic compatibility standards, such as EN 61800-3 and EN 55011.
For further information about the RFI filter model, refer to Table 4.
