1 SAFETY INSTRUCTIONS

This quick installation guide contains the basic information necessary to commission the CFW500. 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 THIS MANUAL AND IN THE PRODUCT

DANGER!
The procedures recommended in this warning aim at protecting the user against death, serious
injuries and considerable material damages.
ATTENTION!
The procedures recommended in this warning aim at preventing material damages.
NOTE!
The information mentioned in this warning is important for the proper understanding and good
operation of the product.
High voltages present.
Components sensitive to electrostatic discharges.
Do not touch them.
The connection to the protection grounding is required (PE).
Connection of the shield to the grounding.
3 PRELIMINARY RECOMMENDATIONS
DANGER!
Always disconnect the general power supply before changing any electric component associated
to the inverter. Many components may remain loaded with high voltages and/or moving (fans), even
after the AC power supply input is disconnected or turned off. Wait for at least ten minutes in order
to guarantee the full discharge of the capacitors. Always connect the grounding point of the inverter
to the protection grounding.
NOTE!
Frequency Inverter may interfere with other electronic equipment. Follow the precautions
recommended in manual available in www.weg.net.
NOTE!
It is not the intention of this guide to present all the possibilities for the application of the CFW500,
as well as WEG cannot take any liability for the use of the CFW500 which is not based on this guide.
For further information about installation, full parameter list and recommendations, visit the website
www.weg.net.
Do not execute any applied potential test on the inverter!
If necessary, contact WEG.
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.
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.
ATTENTION!
The operation of this equipment requires detailed installation and operation instructions provided in
the user's manual, programming manual and communication manuals.
4 ABOUT THE CFW500
The frequency inverter CFW500 is a high-performance product which allows the 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.
In the vector mode (VVW), the operation is optimized for the motor in use, obtaining a better performance in terms
of speed regulation. The scalar mode (V/f) is recommended for simpler applications, such as the activation of most
pumps and fans. The V/f mode is used when more than a motor is activated by an inverter simultaneously
(multimotor applications).

7 RECEIVING AND STORAGE

The CFW500 is supplied packed in a cardboard box. On this package, there is an identification label which is the
same as the one attached to the side of the inverter.
Check if:
The identification of the CFW500 matches the model purchased.
„
Any damages occurred during transportation.
„
Report any damage immediately to the carrier.
If the CFW500 is not installed soon, store it in a clean and dry location (temperature between -25 °C and 60 °C (-77 ºF
and 140 ºF)), with a cover to prevent dust accumulation inside it.
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.

ATTENTION!
When installing two or more inverters vertically, respect the minimum clearance A + B (as per
„
Figure 3) and provide an air deflecting plate so that the heat rising up from the bottom inverter
does not affect the top inverter.
Provide independent conduits for the physical separation of signal, control, and power cables
„
(refer to the Chapter 9 ELECTRICAL INSTALLATION).

8.3 Cabinet Mounting

For inverters installed inside cabinets or metallic boxes, provide proper exhaustion, so that the temperature remains
within the allowed range. Refer to the dissipated powers in Table 3 shows the air flow of nominal ventilation for each frame.

Figure 3 illustrates the procedure for the installation of the CFW500 on the mounting surface.
8.5 DIN-Rail Mounting
In frames A, B and C, the inverter CFW500 can also be mounted directly on 35-mm rail as per DIN EN 50.022. For
this mounting, you must first position the lock
fixing the inverter.
(*) The fastening lock of the inverter on the rail is indicated with a screwdriver in Figure 3.

9.2 Power and Grounding Wiring, Circuit Breakers and Fuses

ATTENTION!
Use proper cable lugs for the power and grounding connection cables. Refer to Table 10 for
„
recommended wiring, circuit breakers and fuses.
Keep sensitive equipment and wiring at a minimum distance of 0.25 m from the inverter and from
„
the cables connecting the inverter to the motor.
(b) DIN rail mounting (Only Sizes A, B, C)
It is not recommended the use of mini circuit breakers (MDU), because of the actuation level
„
of the magnet
ATTENTION!
C
Residual Current Device (RCD):
When installing an RCD to guard against electrical shock, only devices with a trip current of
„
300 mA should be used on the supply side of the inverter.
Depending on the installation (motor cable length, cable type, multimotor configuration, etc.),
„
the RCD protection may be activated. Contact the RCD manufacturer for selecting the most
appropriate device to be used with inverters.
NOTE!
The wire gauges listed in Table 10 sare orientative values. Installation conditions and the maximum
„
permitted voltage drop must be considered for the proper wiring sizing.
In order to meet UL requirements, use ultra fast (for frame sizes A, B and C), and use fuse type J
„
or circuit breaker (for frame sizes D and E) fuses at the inverter supply with a current not higher
than the values presented in Table 10.
