SAFETYNOTICES

This manual contains necessary information for the correct use of the
CFW-10 Variable FrequencyDrive.
This manual has been written for qualified personnel with suitable
training and technical qualification to operatethis type of equipment.
The following SafetyNotices will be used in this manual:
DANGER!
If the recommended Safety Notices are not strictly observed, it can
lead to serious or fatal injuries of personnel and/or material damage.
ATTENTION!
Failure to observe the recommended SafetyProcedures can lead to
material damage.
NOTE!
The content of this manual supplies important information for the
correct understanding of operation and proper performance of the
equipment.
The following symbols may be attached to the product, serving as
Safety Notice:
High Voltages
Components sensitive to electrostatic discharge. Do not touch
them without proper grounding procedures.
Mandatory connection to ground protection (PE)
Shield connection to ground
DANGER!
Only qualified personnel should plan or implement the installation,
start-up, operation and maintenance of this equipment. Personnel
must review entire Manual before attempting to install, operate or
troubleshootthe CFW-10.
These personnel must follow all safety instructions included in this
Manual and/or defined bylocal regulations.
Failure to complywith these instructions may resultin personnelinjury
and/or equipment damage.

NOTICES IN THE
MANUAL
13
CHAPTER 1 - SAFETY NOTICES
NOTE!
In this manual, qualified personnel are defined as people that are
trained to:
1.
Install, ground, power up and operate the CFW-10 according to
this manual and the local required safetyprocedures;
2.
Use of safety equipment according to the local regulations;
3.
Administer First Aid.
DANGER!
The inverter control circuit (CCP10, DSP) and the HMI-CFW-10 are
not grounded. They are high voltage circuits.
DANGER!
Always disconnect the supply voltage before touching any electrical
component inside the inverter.
Many components are charged with high voltages, even after the
incoming AC power supply has been disconnected or switched OFF.
Waitat least10minutes for the total discharge of the powercapacitors.
Always connect the frame of the equipment to the ground (PE) at the
suitable connection point.
CFW-10 drive must be grounded appropriately for safety purposes
(PE).
ATTENTION!
All electronic boards have compon ents that are sensitive to
electrostatic discharges. Never touchanyoftheelectricalcomponents
or connectors without following proper grounding procedures. If
necessary to do so, touch the properly grounded metallic frame or
use a suitable ground strap.
NOTE!
Inverters can interfere with other electronic equipment. In order to
reduce this interference, adopt the measures recommended in
Section 3 “Installation”.
NOTE!
Read this entire manual carefully and completely before installing or
operating the CFW-10.
Do not apply High Voltage (High Pot) Test on the inverter!
If this test is necessary, contact the Manufacturer.

This chapter defines the contents and purposes of this manual and
describesthe main characteristicsof the CFW-10 frequency inverter.
Identification,receiving inspections and storage requirements are also
provided.
This Manual is divided into 9 Chapter, providing information to the
user on receiving,installation, start-up and operation:
Chapter 1 -
Safety Notices.
Chapter 2 -
General Informationsand Receiving the CFW-10.
Chapter 3 -

Chapter 9 -
CFW-10 ratings -Tables and technical information.
This Manual provides information for the correct use of the CFW-10.
The CFW-10 is veryflexibleandallows the operation in manydifferent
modes as described in this manual.
As the CFW-10 can be applied in several ways, it is impossible to
describe here all of the application possibilities. WEG does not accept
any responsibility when the CFW-10 is not used according to this
Manual.
No part of this Manual may be reproduced in any form, without the
written permission of WEG.
It is important to note the Software Version installed in the CFW-10,
since it defines the functions and theprogramming parameters of the
inverter.
This manual refers to the software version indicated on the inside
cover. For example, the Version1.0Xappliesto versions1.00 to 1.09,
where “X”is a variablethat will change due to minor softwarerevisions.
The Software Version can be read in the Parameter P023.

ABOUT THE
CFW-10
The CFW-10 frequency inverter is fitted with the V/F (scalar) control
method.
The V/F (scalar) mode is recommended for more simple applications
suchaspumpandfandrives.Inthese casesonecanreduce themotor
and inverter losses by using the "Quadratic V/F" option, that results in
energysaving.
The V/F mode is also used when more than one motor should be
driven simultaneously by one inverter (multimotor application).
Chapter 9 shows the different power lines and additional technical
information
The block diagram below gives a general overviewof theCFW-10.

RECEIVING
AND STORING
The CFW-10 is supplied in cardboard boxes.
Thereis a nameplateon the outside of the packingbox thatisidentical
to that one on theCFW-10.
Check if the:
CFW-10 nameplate data matches with your purchase order.
The equipment has not been damaged during transport.
If any problem is detected, contact the carrier immediately.
If the CFW-10 is not installed immediately, store it in a clean and dry
room (storage temperatures between -25 °C and 60 °C). Cover it to
protect it against dust, dirtor other contamination.
ATTENTION!
When stored for a long time, it is recommended to power up and
keepthedrive runningfor1 hour everyyear. Make suretousea single-
phasepower supply(50 or 60 Hz) that matchesthedrive ratingwithout
connectingthe motor to its output.Afterpowering up thedrive, keep it
off for 24 hours before using it again.

INSTALLATION
3.1.1

Environment

This chapter describes the procedures for the electrical and
mechanical installation of the CFW-10.
These guidelines and suggestions must be followed for proper
operation of the CFW-10.
The location of the inverter installation is an importantfactor to assure
good performanceand high product reliability. For proper installation,
we make the following recommendations:
Avoid direct exposure to sunlight,rain, high moisture and sea air.
Avoid exposure to gases or explosive or corrosive liquids;
Avoid exposure to excessive vibration, dust, oil or any conductive
particles or materials.
Environmental Conditions:
Temperature : 0 ºC to50 ºC (32 ºF to 122 ºF) - nominal conditions,
except for the 15.2 A model with Built-in filter (0 to 40 °C).
Relative Air Humidity: 5 % to 90 % -non-condensing.
MaximumAltitude: 1000 m (3.300 ft) - nominal conditions.
From 1000 m to 4000 m (3.300 ft to 13.200 ft): with 1 % current
derating for each 100 m (330 ft) above 1000 m (3.300 ft).
Pollution Degree: 2 (according to EN50178 and UL508C).
External dimensions and mounting holes for the CFW-10 shall be
according to figure 3.1 and table 3.1.

Cold Plate Version, installation data (dimensions in mm (in)) – Refer to Section 9.1
The Cold Plate version was designed in order to allow mounting the
“CP”CFW-10frequencyinverter in any heatdissipation surface,since
followingrecommendations are fulfilled.
INSTALLATING THE FREQUENCY INVERTER ON THE HEAT
DISSIPATION SURFACE - STEPS
1.
Mark out the positions of the mounting holes on the backing plate
where the frequency inverter will be located (see in figure 3.1
drawing and hole size).
2.
The surface that is in contact with frequency inverter dissipation
surface must be free of dirt and burr. Standard requirements are:
the backing plate flatness (considering an area of 100 mm
2
(0.15 in
2
))
shall be less than 50
m and the roughness less than

INSTALLATION AND CONNECTION
Figure 3.2 and table 3.2 show free space requirements to be left
around the drive.
Installthe drive on a verticalposition, following the recommendations
listed below:
1)
Install the drive on a flat surface.
2)
Do not install heat sensitive components immediately above the
drive.
ATTENTION!
When there are other devices installed at thetop and at thebottomof
the drive, respect the minimum recommended distance (A + B) and
deflect the hot air coming from the device below.
ATTENTION!
Provide independent conduits for signal , control and power
conductors.(Refer to Electrical Installation).Separate the motorcables
from the other cables.
3.1.3
Mounting
Specification
3.
Use (M4) mounting screws in order tofasten the frequency inver-
ter to the base plate.
4.
After drilling the holes, clean the contact surface of the backing
plate and coat it with a thin thermal paste layer, or with a heat
conducting foil or similar product (approx. 100
m).5.Continue the mechanical installation as indicated in Chapter3.1.
6.
Electrical installation shall be performed as indicated in the
Chapter 3.2.
ATTENTION!
After operation, check P008. This parametermust not exceed 90 ºC.
