Quick Installation Guide
CFW300 Micro Drive
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 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).
The XC10 connector does is not USB compatible, therefore, it cannot be connected to
USB ports.
This connectors serve only as interface between the CFW300 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 CFW300
The CFW300 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 (V V W ) or scalar
(V/f) control, both programmable according to the application.

6 RECEIVING AND STORAGE
The CFW300 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 CFW300 identification label corresponds to the purchased model.
„
Any damage occurred during transportation.
„
Report any damage immediately to the carrier.
If the CFW300 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.

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 inverter according to instruction of the 3.2.4 Grounding Connections the user's manual.
