so as to avoid danger of electric shock.
※ If the power supply is switched off, do not touch the PCB or other parts inside the inverter
within 5 minutes after the keyboard indicator lamp goes off, and you must check by using
the instrument that the inverter has completely discharged all its capacity before you start to
work inside the inverter. Otherwise, there will be the danger of electric shock.
※ The static electricity in human body will cause serious damage to the MOS field effect
transistor in the inverter. Please keep your hands away from the PCB, IGBT and other
internal parts before taking actions to prevent static electricity. Otherwise, faults may be
caused.
※ In use, the earthing terminal ( ) of the frequency inverter must be grounded to the earthing
connections correctly and securely according to the national electrical safety specifications
and other applicable standards.
※ Please don‟t shut off the unit by turning off the power supply. Turn off the power supply
after the motor has stopped its operation.
※ Meet CE standard with EMI filter.
1-3. Application
※ Powtran inverter is generally applied to 3 phase AC asynchronism motors.
※ Powtran inverter is applied to the admisive occasion, the occasion where is not admissive
may lead to fire, electric shock, explosion and so on.
※ If the inverter seizes up when it is applied to the equipment which may lead danger (e.g. lift
tools of transportation, aviation system, saftety equipment, etc), it should be managed
carefully. Do inquire the factory when it happens.
Only the well-trained personnel are allowed to use this unit, and such personnel must read
through the parts of this manual relating to the safety, installation,operation and maintenance
before using the unit. The safe operation of this unit depends on correct transport, installation,
