1-2.Safety precautions
Safety precautions in this manual are divided into the following two categories:
Danger: the dangers caused by failure to perform required operation, may result in
serious body injury or even death;
Caution:the dangers caused by failure to perform required operation,may
result in moderate injury or minor injury, and equipment damage;
Process Type Explanation
Before
installation Danger
★When unpacking, if control system with water, parts
missed or component damaged are found, do not install!
★If packing list does not match the real name, do not
install!
★Gently carry with care,otherwise there is the risk of
damage to equipment!
★Please do not use the damaged driver or the frequency
inverter with missed pieces,otherwise there is the risk of
injury!
★Do not use your hand to touch the control system
components, otherwise there is the risk of electrostatic
damage!
Danger
★Please install the unit on the metal or flame retardant
objects; away from combustible material. Failure to do so
may cause a fire!
★Never twist the mounting bolts of the equipment
components, especially the bolt with the red mark!
When
installing
Note
★Do not let the lead wires or screws fall into the driver.
Otherwise which may cause damage to the driver!
★Keep the driver installed in the place where less
vibration, avoid direct sunlight.
★When two or more converters are installed in a cabinet,
please pay attention to the installation location, ensure the
good heat dissipation effect.
When wiring
Danger
★Must comply with this manual's guidance,any
construction shall be performed by a professional
electrician, otherwise there would be the unexpected risk !
★A circuit breaker must be set between the inverter and
the power supply to separate them, otherwise it may cause a
fire!
★Verify if power is a zero-energy status before wiring,
otherwise there is a risk of electric shock!
★The inverter shall be grounded correctly according to
standard specifications, otherwise there is a danger of
electrical shock!
★Never connect the input power to the inverter output
terminals (U, V, W) . Note that the mark of the terminals,

Process Type Explanation
do not incorrectly connect wires! Otherwise which may
cause damage to the driver!
★Ensure that the distribution line meets the regional safety
standards of EMC requirements. The diameter of used
wire shall refer to the recommendations of this manual.
Otherwise it may cause an accident!
★When connecting to braking resistor,the braking resistor
must be connected to position between terminals (P, RB) of
the inverter
Note
★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!
Before
energizing
Danger
★The inverter's cover plate must close 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!
After
energizing Danger
★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!
During
operation Danger
★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!
