2.2 Transport
This product is a precise device, please handle it with care during the
transport, prevent it from severe collision.
2.3 Storage
This product must be in the packing box before installation. If it won’t
be used for a period, in order to keep it within the warranty of our company
and for the future maintenance, the following matters must be paid attention
to for the storage:
√The product must be put in a dust-free and dry place.
√The temperature of the storage place must be -20℃～+60℃.
√The relative humidity of the storage place must be 0%～95% without frost.
√Avoid putting the product in an environment with corrosive gas or liquid.
√It is better to put the product on a shelf or stand with a proper package.
Notice!
1. Even if the humidity meets the requirements of the criterion, if the
temperature changes quickly, moisture condensation or icing may also
happen, thus the product should not be stored in such place.
2. Do not put the product directly on the ground, but on a proper stand.
If the surrounding environment is very bad, desiccant should be put in
the packing bag.
3. When the storage period is longer than 3 months, the surrounding tem-
perature should not exceed 30℃ , because the electrolytic condenser
is stored with power off, and it will easily degrade if the tempera-
ture is high.
4. When the AC drive is installed in the installation or control panel
but isn’t used, especially in the construction sites or the wet pla-
ces with lots of dust, the AC drive should be removed and put in a
proper environment satisfying the storage requirements mentioned above.
5. The electrolytic condenser is easy to degrade with power off for a
long term. Please do not store the electrolytic condenser with power
off for more than one year.
2.4 Considerations for choices of AC drives
1.Use large capacity above 600 kva electric current transformer and capa-
citor into phase, voltage input side surge current is too large, that could
undermine the input side of AC drives. At the moment the input side must be
installed an AC reactor, in addition to reduce the current, and improve the
effect of the input power.
2.To actuate the special AC drive or one AC drive actuate several motors,
the total rated current of the motor 1.25 times can’t exceed the rated curr-
ent of the AC drive. It is very careful to choose the AC drive.
3.When the AC drive actuate the motor, the startup, the accelerate and
decelerate are limited by the rated current of the AC drive. The starting
torque is small(commercial power directly start 6 times when start current,
when the AC drive starting, the starting current can’t exceed two times), so
when the AC drive use for high torque place(For example Elevator, Blender,
Machine tool ect), the AC drive must increase one or two grade. The optimal
way is increasing one grade of the motor and the AC drive at the same time.
4.To consider that when the AC drive break down and stop the output, the
stop mode for the motor and the mechanical equipment, if they need sudden
stop that must install the mechanical brake.
2.5 Note for parameter setting
1.Because of the highest speed for the digital operation can reach to
400Hz, so when it use in the highest speed place, it can use the speed limit
function limit the output frequency.
2.When the DC braking voltage and the braking time setting too highly,
that may cause the motor overheating.
3.The time for the motor accelerate and decelerate is decided by the
motor rated torque、 load torque、 load inertia ect.
4.When the antistall (STALL) act in the accelerate and decelerate, please
extend the accelerate and decelerate time. If the accelerate and decelerate
must be very fast, and also the inertia load is very big, the AC drive can’t
speed up or stop the motor in requirement time, that must install the braking
resistance(only can shorten the deceleration time) or increase the grade of
the motor and the AC drive at the same time.

3. Mechanical and Electrical Installation
3.1 Installation Environment
3.2 Conditions for Installation
■ The AC drive shall be installed vertically with screws, and shall not be
installed upside down, obliquely or horizontally on a firm structure.
■When the AC drive is running, it will generate heat. To ensure that the
cooling air path is as shown in figure (b). There is a certain space in the
design, and the heat generated will be emitted upward; therefore, do not
install it under the heat-resistant equipment.
■When the AC drive is running, the temperature of the heat sink will rise
to nearly 90 ℃. There for, the mounting surface on the back of the AC drive
must be made of materials that can withstand higher temperature.
■When the AC drive is installed in the control panel, ventilation and heat
dissipation shall be considered to ensure that the ambient temperature of the
AC drive does not exceed the specification value. Do not install the AC drive
in the airtight box with poor ventilation and heat dissipation.
■When installing multiple AC drives in the same control panel, it is reco-
mmended to install them horizontally side by side in order to reduce the
thermal impact on each other. If it has to be installed up and down, the par-
tition board must be set to reduce the impact of heat generated at the lower
part on the upper part.
Notice!
1、Do not let all kinds of fibers, paper, wood chips (chips) or metal
fragments and other foreign matters enter the AC drive or adhere to
the cooling fan.
2、Installed on structures that will not burn, such as metal, or fire
accidents may occur.

3.5 Basic Wire Layout
■ The power supply must be connected with the terminals of the main loops
of AC drive R/L1, S/L2, T/L3. If the power supply is improperly connected
with other terminals, the AC drive will be damaged. Besides, check whether
the voltage/current of the power supply is within the allowable range indi-
cated on the nameplate.
■The grounding terminals must be grounded well, on the one hand it can
prevent electric shock or fire, and on the other hand it can reduce the noise
interference.
■ Connect the terminals with wires, ensure the high reliability of the
connection.
■After finishing the wire layout, check the following things:
1. Are all the connections correct?
2. Is there any connection left out?
3. Is there any short circuit or line-to-ground short circuit between
the terminals and the connecting wires?
When the power is on, if the connections need to be changed, first the
power supply should be turned off, and the filter capacitor of the DC part
of the loop will need some time to discharge electricity. The work only can
begin after the completion of electricity discharge. Besides, because of the
residual voltage, sparks may be generated when there is a short circuit, thus
it’s better to conduct the work under voltage-free conditions.
Notice!
1.Grounding wire must be connected, or electric shock or fire may happen.
2.The wiring work should be done by the professional technicians.
3.Start the work after confirming that the power is OFF or electric shock
may happen.
Basic Wire Layout Graph
The wires of AC drive can be divided into main loop and control loop.
Users can open the upper cover and see the terminals of main loop and control
loop. Users must lay the wires according to the figure below to ensure the
accuracy of connections.
Notice!
1.Grounding wire must be connected, or electric shock or fire may happen.

3 9 Main Circuit Connection Functions.
General precautions for main loop wiring:
■Please do not connect the AC with the output terminal (U/T1, V/T2 and
W/T3) of AC drive; otherwise it may cause AC drive damage.
■Ensure that the screws of the main loop terminals are tightened to
prevent the sparks caused by the loose screw due to vibration.
■The wires of main loop and those of control loop must be separated to
avoid misoperation. If an intersection is needed, make them intersect with a
right angle.
■ Please use isolated cable and conduit, and connect with the two ends
of the shielding layer or conduit with ground.
■If the installation place of the AC drive is extremely sensitive to
interference, please add an RFI filter in a place with a distance from the AC
drive as close as possible. The lower the carrier frequency of PWM is, the
less the interference there will be.
■ When the AC drive is equipped with a residual current circuit breaker
for the protection against electric leakage, please select the ones with
action current over 200mA and action time over 0.1s to avoid the misoperation
of residual current circuit breaker.
■ The AC drive, motor and wires will cause noise interference. Pay
attention to the surrounding sensors, and check whether there is misoperation
of the equipment to prevent the accidents.

Description of the power supply input terminals of the main loop
(R/L1 S/L2 T /L3)
■Ascertain the voltage of power supply and the maximum current that can
supply.
■Main loop terminal R/L1, S/L2, T/L3 is connecting to a three-phase AC
power through the circuit (wiring) protection with circuit breakers or earth
leakage protection circuit breakers, without considering phase sequence con-
nection.
■To cut off power and avoid accident when AC drive protection power is
on, electromagnetic contactor to connecting to the circuit is necessary. (The
two ends of the electromagnetic contactor should be equipped with R-C surge
absorber).
■ Don't use main loop ON/OFF switch to start and stop AC drive. Use
loop control terminal FWD, REV or RUN/STOP button on the control panel to
start and stop AC drive. If you must use main power supply ON/OFF switch to
start and stop, do it no more than 1 time within one hour.
■Do not connect the 3-phase power supply machine with the single-phase
power supply.
Output terminals of AC drive(U/T1. V/T2. W/T3)
■ Connect AC drive output terminal to 3 phase motor according to correct
phase order. If motor rotates in wrong direction, change any 2 phase of U,V,W.
Forward
running
■The output terminal of AC drive can’t be connected to the inlet phase
capacitor or surge absorber. If the wires are very long, it should be connec-
ted with the AC reactor on the output end.
■There is high frequency current in the extra long wire between motor
and AC drive. This may cause AC drive over flow and stop. Besides, long wire
increase leaking current, this leads to poor precision of current value. AC
drive≤3.7KW choose wire less than 20 meters to motor, less than 50 meters
for AC drive over 3.7 KW. If the wire is very long a wave filter connected to
the output side AC reactor is necessary.
■Used insulation strengthened motor.
Grounding terminals of AC drive (EG)
■For safety and noise reduction, the grounding terminals of AC drive
should be well grounded.
■The grounding wire of AC drive can't be grounded together with the
machines with heavy current load e.g. the electric welding machine and high
power motor, they should be grounded separately instead.
■In order to prevent electric shock and fire, the external metal grou-
nding wires of electric equipment should be wide and short, and connected to
the special grounding terminals of the AC drive system.
■If there is more than one AC motor speed controller connecting with the
ground, Please make sure that is does not form grounding loop, shown as the
following figures:

3.10 AC drive control terminal connections Analog input terminals (FS, FV, FI, FC)
■The connection with analog signal is especially easy to be influenced
by the interference of external noise, thus the wire should be as short as
possible (less than 20m), and shielding wire should be used. The outer wire
mesh of the shielding wire should be basically grounded, but if the inducing
noise is very loud, it is better to connect it to the FC terminal.
■For the need of using contact in this circuit, the double-fork contact
which can process weak signals should be used. Besides, the terminal FC should
not adopt contact control.

Output terminals of transistor (Y3,Y4)
■While controlling the input of contacts, in order to prevent bad con-
tact, the contacts that have high reliability for the contact with weak sig-
nals should be used.
■The polarity of the external power supply should be correctly connected.
■While connecting the control relay, the surge absorber should be conne-
cted with the two ends of field coil. Please ensure that the polarity is corr-
ectly connected.
■While connecting with the external analog signal follower, sometimes
the interference caused by the analog signal follower or the AC drive will
lead to misoperation, in such conditions, the capacitor and the magnetic core
of ferrite may be conncted to the external analog follower, as shown below:
Others
■It's best to use the shielding wires as control wires, the isolation
network divested segment before the terminals should not be exposed.
■The wires of control terminals should keep away from the wires of the
main loop, or misoperation may be caused due to noise interference. If an
intersection is needed, make them intersect with a right angle.
■Generally the control wires don't have good insulation. If the insula-
tion layer is broken due to some reason, high voltage may enter the control
circuit (control panel), leading to circuit damage, equipment accidents or
personal Danger .
■The control wires in the AC drive should be fixed properly to prevent
them from the direct contact with the charge-carrying part of the main circuit
(e.g. the terminal strips of the main circuit).

4.2 Check and Test before Operation
The following matters should be paid attention before the operation:
■ Check if wire connection is correct. Confirm AC drive output terminal U, V, W is not
connected to POWER and the ground terminal E(G) is grounded well.
■ Confirm there is no short circuit within every terminal and electricity naked part.
■ Confirm all terminals connection and joints are tight and not loose.
■ Ensure that the motor isn't connected with loaded machine.
■ Before turning the power on, ensure that all the switches are in the disconnected state to guar-
antee that the AC drive won't start or operate abnormally when the power is on.
■ The power supply can only be turned on after the upper cover is installed.
■ It is forbidden to operate the switch with wet hand.
■ Display of the keypad panel (no indication of faults)
■ The cooling fan installed in the AC drive should work normally.

3.Press FWD or to start and to low down and stop.
4.Check the following before running:
Check whether the rotation of motor is correct.
Check whether the rotation of motor is steady (without abnormal noise or vibration).
Check whether the acceleration / deceleration are steady.
If there is no abnormality, perform the test run with frequency increased.
If no abnormality happens in the test run above, the formal operation can be started.
Notice!
If there is any abnormal phenomena occured , stop AC drive immediately. Consult “fault
diagnosis”to find the problem. When AC drive stops, terminal L1/R1, L2/S, L3/T is still with
power if main circuit is not switched off.
Any touch onto terminal U, V, W will be shocked. Besides, wave filter capacitor is still full
of charging voltage and need certain period of time to discharge, if main circuit power is off.
Touch inner AC drive circuit only after power and the DC circuit voltage tested by DC circuit
voltage meter is below safety voltage.
