The diameter of 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 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!

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!
