2INSTALLATION
!WARNING
l Toguarantee the safeoperationoftheequipment itmust be installed and commissioned properlyby qualified
personnel incompliancewith warnings laiddown in theseoperating instructions.
l Take particular noteofthegeneralandregional installationand safetyregulations regardingwork onhigh
voltage regulations,as wellas the relevant regulations regardingthecorrectuse oftools and personal protective
gear.
l Makesure thattheunobstructed clearanceforeach ofthecooling inlets and outlets aboveand belowthe inverter
is atleast 100mm.
l Makesure thataspaceof40mm is kept freeatthesides oftheinvertertopermit thecooling airtoescapefrom
the sideslits.
l Ensure that thetemperaturedoes notexceedthespecifiedlevelwhentheinverterisinstalledincubicle.
l Avoid excessivevibrationand shaking oftheequipment.
l Donotbe obstruct the cooling fanthatinstalledonthe inverter,itis used tobuild properairflowforheatsink
thermo dissipation. And donottouch the fan hole when it is running.
NOTE:Pleaseconsider thepossibleuse ofoptions, such as RFIsuppressionfiltersattheplanningstage.
!CAUTION
1) Toopen the upper cover ofthe inverter, followtheserules:
2) Cutoff the inputsupply power
3) Wait5minutes until internalcapacitorcompletelydischarged
4) Use small minusscrewdriver,plugintothelock holeslocatedattheloweredgeofthecover.Then the cover
is freetoopen.

2.2PowerTerminal
Theuppercovermustbe removedinordertoconnecttheelectricalleads.
Basically, thePowerterminals aredividedintothree portions:
l ThePowerlineinput, (R, S, T) receivespowerfortheoperationof theinverter.
l TheMotorlineoutput,(U, V, W) deliversVariableFrequency output tomotorleads.
l Brake resistorconnecttoB,P,terminal.(Theinscriptionof terminals maybe PRorPB.)
Note: Must connectEarth properly.
!WARNING: Neverconnect powerline to U, V,W,P, N, B,PR,BR.
2.3Connect Power line input toInverter
!WARNING and CAUTION
l Between thepowerlineand theinverter,add NFBforsystemprotection.
l Therearestaticsensitivecomponents inside thePrinted Circuit Board. Avoid touching the boards or
components with yourhands ormetal objects.
l Onlytheterminalscrews may betouched withtheinsulated screwdrivers when connectingtheleads.
l Makesure toconnectthepowerterminals tight and correctly.
l Makesure thatthepower source supplies thecorrectvoltage and isdesigned for thenecessarycurrent.
l Makesure themotoris configured tomatchtheinputvoltage.
l ProtectiveEARTH terminal marked with must be connected properly.
l Take care that the appropriatecircuit breakers with thespecifiedcurrentratingare connectedbetweenthe
