Chapter 1 Inspection and safety precautions
3
●Before switching on the inverter power , please make sure the
cover plate of inverter is firmly installed , and the motor is allowed
to restart . Make sure the rated voltage of inverter is consistent with
the power supply voltage.
●If the main circuit power voltage is used incorrectly, there will be
a danger of fire.
●Do not connect the input power source to the output terminals
(U,V,W) of inverter . Otherwise there is a risk of damage to inverter.
●Do not open cover plate after energizing. Otherwise there is a risk
of electric shock.
●Do not touch any input and output terminals of the inverter.
Otherwise there is a risk of electric shock.
●Do not remove the cover of inverter or touch the printed circuit
board when it is power on , otherwise there is a risk of electric shock!
●Please do not change the inverter manufacturer parameters.
Otherwise it may cause damage to this unit.
●If you need to identify the parameters, please pay attention to the
danger of injury during motor rotation. Otherwise it may cause an
accident.
●Do not touch the cooling fan and the discharge resistor to feel the
temperature. Otherwise it may cause burns.
●Non-professional personnel is not allowed to detect signal when
operating. Doing so may cause personal injury or damage to this
unit!
●When the inverter is operating, you should avoid that objects fall
into this unit.Otherwise cause damage to this unit.
●Do not start/stop the driver by switching on/off contactor.
Otherwise cause damage to this unit.
●Do not perform repairs and maintenance for the live electrical
equipment. Otherwise there is a risk of electric shock.
●The repairs and maintenance task can be performed only when
the inverter bus voltage is lower than 36V,Otherwise, the residual
charge from capacitor would cause personal injury.
●Non-well-trained professional personnel is not allowed to perform
repairs and maintenance of inverter. Doing this may cause personal
injury or damage to this unit.
●After replacing the inverter, parameter settings must be redone, all
pluggable plugs can be operated only in the case of powering off.
●Do not power on and operate the damaged inverter, otherwise it
will enlarge the damage.
1-3.Precautions
Motor insulation
inspection
Please perform motor insulation inspection for the first time use,re-use
after leaving unused for a long time as well as regular check, in order to
prevent damage to the inverter because of the motor's winding
insulation failure. Wiring between motor and inverter shall be
disconnected, it is recommended that the 500V voltage type megger
should be adopted and insulation resistance shall be not less than 5MΩ.
If the rated capacity of the selected motor does not match the inverter,
especially when the inverter rated power is greater than the motor
rated power, be sure to adjust the motor protection parameter values
inside inverter or install thermal relay in the front of motor for motor
