inverter, this product has been tested before leaving factory. Otherwise
it may cause an accident!
● The inverter's cover plate must be closed before power on. Otherwise
it may cause an electric shock!
● Wiring of all external accessories must comply with the guidance of
this manual, please correctly wiring in accordance with the circuit
connection methods described in this manual. Otherwise it may cause
an accident!
● Do not open cover plate after energizing. Otherwise there is a risk of
electric shock!
● Do not touch the driver and peripheral circuits with wet hands.
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!
● The inverter automatically perform the safety testing for the external
strong electrical circuit in the early stages of energizing, therefore
never touch the driver terminals(U, V, W) or motor terminals,
otherwise there is a risk of electric shock!
● If you need to identify the parameters, please pay attention to the
danger of injury during motor rotation. Otherwise it may cause an
accident!
● Please do not change the inverter manufacturer parameters.
Otherwise it may cause damage to this unit!
● 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
plugable plugs can be operated only in the case of powering off!
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
megameter 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
