CHAPTER 1 - SAFETY NOTICES
NOTE!
Inthis manual,qualifiedpersonnelaredefinedaspeople thatare
trainedto:
1. Install,ground,power upandoperatetheCFW-08according
tothis manual andthelocalrequiredsafetyprocedures;
2. Useof safetyequipmentaccordingtothelocalregulations;
3. Administer FirstAid.
DANGER!
Theinvertercontrolcircuit(ECC3,DSP)and theHMI-CFW08-P
arehigh voltagecircuitsandare notgrounded.
DANGER!
Always disconnect the supply voltage before touching any
electricalcomponentinsidetheinverter.
Many components are charged with high voltage and/or in
movement (fans), even after the incomingAC power supplyhas
beendisconnectedorswitchedOFF. Waitatleast10minutesfor
the total discharge of the powercapacitors.
Alwaysconnecttheframeofthe equipmenttotheground(PE)at
thesuitableconnectionpoint.
ATTENTION!
All electronic boards have components that are sensitive to
electrostatic discharges. Never touch any of the electrical
components or connectors without following proper grounding
procedures. If necessaryto do so, touch the properly grounded
metallic frame oruse asuitable ground strap.
NOTE!
Inverterscaninterferewithotherelectronicequipment.Inorderto
reduce this interference, adopt the measures recommended in
chapter3-InstallationandConnection.
NOTE!
ReadthisentiremanualbeforeinstallingoroperatingtheCFW-08.
Do not apply high voltage (high pot) test on the inverter!
If this test is necessary, contact Eliwell.

This manualis dividedinto7 chapters, providing information
to the user on how receive, install, start-up and operate the
CFW-08.

This manual provides information for the correct use of the
CFW-08. This frequency inverter is very flexible and allows
the operation in many different modes as described in this
manual.

It is important to note the software version installed in the
CFW-08,sinceit definesthefunctionsandtheprogramming
parameters of the inverter.
This manual refers to the software version indicated on the
insidecover.Forexample,theversion3.0Xappliestoversions
3.00 to 3.09, where “X” is a variable that will change due to
minor software revisions. The operation of the CFW-08 with
these software revisions are still covered by this version of
themanual.
The software version can beread in theparameter P023.
