Safety Signs
Please read the safety manual and instructions carefully before using the product, otherwise
•
there may be danger of personal injury or product damage!
•
Do not touch the terminals or remove the cover when the power is on or within 10 minutes
after the power is turned off, otherwise there is a risk of electric shock!
Danger
Failure to follow the instructions may result in danger, which may lead to serious injury or even
death.
1. If you find that the package has water ingress, parts are missing or parts are damaged when unpacking, please
do not install it!
2. Please install it on flame-retardant objects such as metal, away from combustibles, otherwise it may cause a
fire!
3. Do not twist the fixing bolts of the equipment components at will, especially the bolts with red marks!
4. The instructions of this manual must be followed and the construction must be carried out by professional
electrical engineers, otherwise unexpected dangers will occur!
5. The inverter and the power supply must be separated by a circuit breaker (it is recommended to use a
specification greater than or equal to and closest to 2 times the rated current), otherwise a fire may occur!
6. Please make sure that the power supply is in a zero energy state before wiring, otherwise there is a risk of
electric shock!
7. Please correctly, standardized and reliably ground the inverter according to the standard, otherwise there may
be a risk of electric shock and fire!
8. If the indicator light does not light up and the keyboard does not display after power-on, please turn off the
power switch immediately. Do not touch the inverter R, S, T and any terminals on the wiring terminals with
your hands or screwdriver, otherwise there is a risk of electric shock. Contact our customer service staff
immediately after disconnecting the power switch.
9. At the beginning of power-on, the inverter automatically performs a safety test on the external strong current
circuit. At this time, you must not touch the inverter U, V, W terminals or motor terminals, otherwise there is a
risk of electric shock!
10. Do not disassemble any parts of the inverter when the inverter is powered on.
11. Do not touch the cooling fan, radiator and discharge resistor to test the temperature, otherwise it may cause
burns!
12. Non-professional technicians should not detect signals during operation, otherwise it may cause personal
injury or equipment damage!
13. Do not repair and maintain the equipment with power on, otherwise there is a risk of electric shock!
14. Cut off the main circuit power supply and confirm that the keyboard display interface is off for at least 10
minutes before performing maintenance and repair on the inverter, otherwise the residual charge on the
capacitor will cause harm to people!
15. Personnel who have not received professional training should not perform maintenance and repair on the
inverter, otherwise it will cause personal injury or equipment damage!
16. The synchronous machine will generate electricity when rotating. In the event of a power outage, you must
wait 10 minutes after the motor stops before performing maintenance and repair on the inverter. Otherwise,
there is a risk of electric shock!
Inverter standard wiring diagram
It is recommended to use wires with a diameter of 0.5~1mm2 for the control circuit wires

Please use a PH0 cross screwdriver to install the control circuit terminals, and the tightening torque

is 0.5N.m.
Jumper and DIP switch
Position No. Logo
When the jumper is placed at the NPN end, the X terminal input is
J10 in NPN mode. When the jumper is placed at the PNP end, the X
terminal input is in PNP mode.
When the jumper is placed at the V terminal, the analog output M1
J7 is a voltage type output. When the jumper is placed at the I
terminal, the analog output M1 is a current type output.
When the jumper is placed at the V terminal, analog input AI2 is a
J8 voltage input. When the jumper is placed at the I terminal, analog
input AI2 is a current input.
When the DIP switch is turned to ON, a 120Ω terminal resistor is
S1 added to the RS485 bus. When the DIP switch is turned to OFF, the
terminal resistor is disconnected.

The functions of the main circuit terminals of the EM730 series inverter are shown in the following table.
Please connect correctly according to the corresponding functions.
Terminal number
AC power input terminal, connected to three-phase AC power, for single-phase
R/L1、S/L2、T/L3
power input, any two terminals can be connected
U、V、W Inverter AC output terminal, connected to three-phase AC motor
They are respectively the positive and negative terminals of the internal DC bus,
connecting the external brake unit
Braking resistor connection terminal, one end of the braking resistor is connected,
、PB
and the other end is connected to PB
DC reactor terminal, used when EM730-132-3 and above models are connected to
P、
an external DC reactor
Ground terminal, for safety, please be sure to connect to the protective ground
Digital tube display keyboard operation mode
The LED keyboard menu is divided into monitoring level (level 0), menu mode selection level (level 1),
function code selection level (level 2), and parameter value level (level 3) from low to high. The menu level
mentioned later in this manual is represented by numbers.
There are 5 parameter display modes: full menu mode (--A--), used to display all function codes;
user-defined mode (--U--), used to display only the function code selected by the user through the F11
group; non-factory value mode (--C--), used to display only function codes different from the factory value,
fault information display mode (--E--), used to display the current fault information; version information
mode (--P--), used to display the software and product serial number.
The keyboard displays the first monitoring parameter of level 0 by default when it is powered on. Press
the ESC key to enter the level 1 menu. In the level 1 menu, you can select different menu modes
by rotating the keyboard encoder. The menu mode selection operation process is shown in Figure 4-1
Figure 4-1 Menu mode selection operation flow chart
Full menu mode (--A--)
In full menu mode, press ENTER
ENTER to enter level 3 menu to view or modify function codes. Except for a few special function codes,
function codes that general users need to use can be modified.
Example: In full menu mode, the entire operation process from power-on initial state to changing the
value of function code F03.28 to 5.28 is as shown in the figure below.
Confirmation method
Please check the nameplate on the side of the inverter.
Check the overall appearance to see if there is any damage
during transportation.
If necessary, check with a screwdriver.
