used wire shall refer to the recommendations of this
manual. Otherwise it may cause an accident!
● Never directly connect braking resistor to the DC bus
P(+) and P(-) terminals. Otherwise it may cause a fire!
● Encoder must use the shielded wire, and the shielding
layer must ensure the single-ended grounded!
● Please confirm whether the input power voltage is
same as the inverter rated voltage; wiring positions of
power input terminals(R, S, T) and output terminals(U,
V, W) are correct or not; and note that if there is a short
circuit in the peripheral circuit connected to driver, if
Note
the connected lines are tight, otherwise it may cause
damage to the driver!
● Do not need to perform withstand voltage test for any
part of the 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
Danger
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
Danger
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!
Danger
● 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
