Chapter 1 Production Overview
1.1 Precautions on commodity inspection and storage
Before delivery, all goods are under strictly quality control and well
packed. However it may damage during the international transportation,
please check them carefully:
1. Check the package condition to make sure no damage happened
during transportation
2. Open the package and find out the user manual
3. Check the nameplate information on side of the inverter, be sure you
get the right product or spare parts
For any problem you may have, please contact your supplier!
STORAGE
Inverter should be packed and stored in ventilate and dry place. Keep
it away from corrosive gas, liquid and stained conditions.
The relative Humidity suggest to be 0% - 95% , no condensing,
The allowed temperature range is from -25℃to 65℃
Transportation Cautions:
Temperature range is from -25℃to 70℃
Relative Humidity is allowed to be 5% - 95%
Atmospheric pressure is allowed to be from 70kpa to 106kpa.

2.6 Safety Considerations
1. Please use right wires according to relative laws. When the distance
between inverter and motor is over than 25meters, should raise wiring
standard.
2. Between the three-phase AC input power and main circuit terminal
(R,S,T) there must be a fuse switch. Make an electromagnetic contactor
in series to cut off power before the inverter steer its protection.
3. Ground terminal to the first grounded wiring.
The ground impedance must be less than 100R. Or make the ground
wire dimension is same with the main circuit wires.

Chapter 2 Installation and wiring
9
4.The inverter should not joint ground with other high current loads, must
be separated.
5.The ground wire should be shorter.
6.When the inverters are common ground, don’t make a ground loops.
7.Confirm the voltage and maximum current.
8. The power indicator on the side of inverter shows the voltage inside
the inverter.
9.When the power indicator is lighting ,do not connect or disassemble
wires.
10. The SD4000 series is not equipped with the brake resistor. In the
occasion of frequently starting or stopping inverters, please install brake
resistor or unit.
11.Please connect the inverter’s terminal U,V,W with motors’
correspondingly. If the FWD lights, means the inverter is forward rotation;
if the REV lights, means the inverter is reversing. When the inverter is
forward rotation and motor is reversing,swap any two terminals of the
motor.
Do not connect the AC power with output terminals of the inverter.

3.1 Operation panel description( digital keypad is optional)
I. Digital Keypad Operation
This digital keypad module includes two parts: display panel and keypad.
The display panel allows the user to program the AC drive, as well as
view the different operating parameters. The keypad is the interface for
user and inverter.
. The following description refers to different parts.
LED indication
Red lamp lights during RUN,
STOP, JOG, FWD, or
REV operation.
LED display
Indicates frequency, motor
current
and alarm contents.
Forward / Reverse key
Selects FWD or REV
operation.
Jog key
While pressing this key, jog
speed is available.
Run key
Starts operation.
Program / Reset key
Selects normal mode or
program mode. Displays
the inverter status
Function / Data key
Displays the motor
drive status, or sets
parameters under the
requirement
Stop key
Stops operation.

KEY
Functions
For normal operating or programming mode (the key is
always valid)
. Must select programming mode to modify parameters
If the drive is shut down due to a fault occurs, after
troubleshooting, press this button will clear the error
message.
This is data setting key. In normal operating mode, press
this button to display the drive status information, such as
frequency command, output frequency and input current;
in programming mode, press this key to display the
parameter content. Then Press this button again will save
the changed parameters to the internal memory
Select forward or reverse operation. Press this button , the
motor will decelerate to 0HZ and change direction, but
motor will not restart automatically after the shutdown. An
external terminal can control motor forwarding or
reversing, when modify Pr.001 to "d0001" or "d0002"
Press this button ,the motor will run at jog frequency as set
by the parameter specified under Pr.23
start running key (if set to an external terminal control,
press this key is invalid)
Stop key.
Press the “Up” and “Down” button to select or modify
parameters ..
Note: Pressing the “Up” or “Down” button momentarily
changes the parameter settings in increments. Press and
hold these keys to rapidly run through the possible
