1.6 Precautions
1. The inverter just applies to general triple-phase AC induction motors or variable
frequency motors. The installation environment should be well ventilated.
2. It is a normal phenomenon that temperature and noise of the motor raise a little
higher than power frequency when use the inverter.
3. General motors can’t work long under low-speed.
4. Output terminal of the inverter cannot be connected with RC absorbing device,
such as capacitor, varistor, etc.
5. If install the contactor between the inverter and the motor, must ensure that the
inverter does not output when the contactor is on-off. Otherwise, it will damage
the inverter.
6. The inverter should be used derating if the altitude is higher than 1000 meters.
Derate 10% when the altitude rises 1500 meters.
7. The inverter is as industrial waste when scrap it. Please be careful:
（1）Inner polymer capacitors probably explode if set it on re.
（2）Plastic pieces may produce toxic gases when burn it.

Danger
Caution
1 Before wiring, please conrm the cut-off of input power supply.
Risk of electric shock and re.
2 Wiring operations must be carried out by electric engineerting specialists.
Risk of electric shock and re.
3 Ground terminal must be reliably grounded.
(380V class:especially the third
ground)Risk of electric shock and re.
4 After connecting with the terminal of emergency stop, be sure to check the
validity of actions.Risk of injury.(The responsibility of wrong wiring is
undertaked by users.)

3.4.3 Precautions of main circuit wiring
1. Installation of ELCB
As the inverter’s output is high-frequency PWM signal, the inverter will generate
high-frequency leakage current, please select Y2 type delay leakage circuit breaker
with above 30mA current sensitivity; if use ordinary ELCB, please select ELCB with
above 200mA current sensitivity.
2. Connection with terminal blocks
The phase sequence of input power supply is irrevelant to R(L1), S(L2), T phase
sequences of terminal block, so it can be any connection.
3. Setting of AC reactor or DC reactor
When the input power is connected with capacitive load, it will generate high peak
current in power grid.
If don’t take appropriate measures, the peak current may damage inverter rectier
and other power modules.
When there is high peak current in power grid, please connect 3PH AC reactor
(optional) on the power input side of inverter, or install DC reactor on the terminal of
DC reactor.
Therefore, it not only suppresses peak current, but also improves power factor.
4. Setting of Surge Protection Device (SPD)
When there is inductive load near the inverter (electromagnetic contactor,
electromagnetic valve, electromagnetic coil, electromagnetic circuit breaker), please
install SPD at two ends of its coil.
5. Wiring of inverter and electric motor
Please check whether rotate forwards when conrm the command of forward.
When the motor is reverse rotation, exchanging any two of U, V, W output
terminals can change rotation direction of the motor.
Use jog function to conrm forward and reverse rotations.
User Manual of SY5000 series AC Drive Wiring
~27~
6. Absolutely prohibit the connection of power supply wire and output terminal
Don’t connect the input power line to the output terminal.
If you input the power at the output terminal, the internal components of inverter
will be damaged.
7. Absolute prohibit short-circuit or grounding of output terminal
Do not directly touch the output terminal. Do not short the output line with inverter
housing. Otherwise, there will be danger of electric shock and short circuit.
In addition, don’t short the output line.
8. Absolutely prohibit the use of phase-shift capacitor
Don’t connect the capacitor in the output circuit. It will cause the damage of the
inverter.
9. Absolutely prohibit the use of electromagnetic switch
Don’t connect electromagnetic switches and electromagnetic contactors.
Otherwise, inverter surge current will cause protection action, and that will damage
interial components when it’s serious.
10. Wiring distance between inverter and motor
The longer wiring distance between the inverter and the motor, the higher high-
harmonic leakage current of the cable.
Leakage current will negatively impack the inverter and near equipments. Then it
should minimize the leakage current.
Wiring distance and carrier frequency are as shown in Table 3-3:

Below 50m Below 100m Above 100m
Carrier frequency Blow 12KHz Below 10KHz Below 5KHz
Function code of parameter b-026
≤12.0 ≤10.0 ≤5.0
11. Ground connection
①
Ground terminal, please connect the ground.
220V series：type 3 ground（grounding resistance is less than 100Ω）
380V series：special type 3 ground（grounding resistance is less than 10Ω）
②
Don’t share the grounding line with welding machines or power equipments.
③
Please use the grounding wire according to electrical equipments technical
standards. And the distance from the ground is as short as possible.
User Manual of SY5000 series AC Drive Wiring
~28~
④
Don’t form the grounding line to a loop in the place when use two or more
inverters. Correct and wrong grounding methods are as shown in Figure 3-5.
Figure 3-5 Grounding comection
3.5 Wiring of control circuit terminal
In order to reduce interference and attenuation of control signal, wire length of
control signal should be less than 20m. The interval distance between wire length
and power line should be more than 30cm. Control signal line should be twisted-pair
shield cable.
