1-2. Safety Precautions
※
Never connect the A.C. power supply to the output terminals (U, V, W)
of the frequency inverter.
※
Fix and lock the panel before supplying power so as to avoid the
danger caused by the poor capacity or other components inside the
inverter.
※
After the power supply is switched on, do not perform wiring or check,
etc.
※
Don't touch the circuit boards or its parts or components in the inverter
when it is powered, 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 (E or
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
