1.Function and Feature
SSXA/SSXB series LED AC motor soft starter is new type starting equipment with advanced
international level. This equipment designed and manufactured by the technique of power
electronics microprocessor and modern control theory. This equipment can limit the start current
efficiently when the asynchronous motor starts. It is widely applied in the field such as winding
machine, pump, transition and compressor etc. It is the ideal product to replace the traditional
voltage dropping start equipment such as star/triangle conversion, self-coupling voltage dropping,
magnetic control dropping voltage etc.
Function
◆ Reduce the starting current of motor; reduce capacity of power distribution; reduce the
investment cost；
◆ Reduce the start stress; prolong the operation lifetime of the motor and correspond equipment；
◆ Smooth and steady starting and soft stopping; The Water hammer and surge can be avoid；
◆ Several sorts of starting mode, wide range setting of the current and voltage. It can be used
in a lot of load conditions, so the technic can be improved；
◆ Perfect and reliable protection; The safeguard of the motor and relative equipment can be
achieved effectively；
◆ It can be used in the state in which motor should star and stop frequently。
Feature
◆ Starting Mode：Based on the load characteristics, different starting mode can the related
parameters can be selected. So the best starting effect can be gained；
◆ Technical Performance：The higher performance microprocessor and software are used, so the
control circuit is simplified. The best perform speed can gained without the adjustment of the
circuit parameters；
◆ Reliability：All the electronic components of this product are selected strictly. Additionally,
the main control board is tested in high temperature environment above seventy-two hours. The
reliability of this product can be guaranteed
◆ Structure：The modularization structure and up-in-down-out wiring mode are adopted. It is
easy to used and integrated；
◆ Multi-Protection：The motor protection circuit is not be added if the single product is in
used. Because of this product have multiple protection functions (Such as over-current,
overload, phase-fault, overheat and so on). So the cost can be reduced, the circuit can be
simplified.
◆ Keyboard：Operation of the keyboard is easy. User can set and modify the parameters (for
example: starting, stopping, running, protection) by this keyboard according to different load

conditions.
◆ Analog signal output：4-20mA analog sign output l is provided；
◆ RS485 provide RS485( Modbus communication protocol)communication；
◆ Actual power setting：When the rate power of Soft Starter is higher than the power of actual
load, soft starter can be matched to the actual load by modifying the actual current parameter.
So the parameters about starting、running and protection are correct
2.Product Type and Inspection
Each SSXA/SSXB series soft starter is tested. Only the starter that passes the function and
running test can leave the factory. After receiving the equipment, the user should inspect it
according the steps described below. Please notify the supplier immediately if you find any problem
◆ Check the nameplate：Check the item(s) nameplate catalog number against the purchase order.
Make sure that the equipment you received is matched with the product you ordered。
◆ Inspect whether or not the product is damaged through the delivery, for example: Inner parts
fall off, She11 is deformed or depressed, the wires are loose etc.
◆ Quality certificate and user manual: The package of each soft start includes quality
certificate and user manual.
◆ SSXA series soft starter has built-in bypass contactor.

3. Environment and Installation
3.1 Environment
The environment is important to the equipment life. So please install the soft starter on the
site described below
◆Operation Condition for the standard products
Power Supply: Urban power, self-provided substation, diesel generating sets
Three-phase AC: 380V or 660V or 1140V (-10%, +15%), 50Hz.
(note：voltage level should be matched to the rate voltage of the actually motor, user should
explain the voltage level in the purchase order if it is special.)
Motor: Squirrel cage asynchronous motor. (Please explain in the purchase order if it is special)
Start frequency: less than 20 times per hour for Standard products (Please explain in the purchase
order if the motor should be start more frequent)
Cooling: Natural air-cooled or Fan air cooling
IP Code: IP20
Environment condition: If the altitude is above 2000 M, user should select the higher power
product.

3.2 Installation
◆Direction and Distance
The product must be vertically installed. There should be enough space to dissipate the heat,
as shown in figure 3-1. For the cabinet product, there should be a certain distance between back
door of the product and wall. Therefore it is easy to maintain.

◆Cabinet installation
If the product is installed in the cabinet, make sure there are good ventilation in the cabinet.
The products can be installed vertically or horizontally. Horizontal layout shows in Figure 3-2.
Vertical layout shows in Figure 3-3. User can adopt any of them.
Note: If the vertical layout is adopted (especial in fan air cooling mode), clapboard should be
installed between them to avoid that the upper starter is affected by heat generated by the lower
starter.

4. Operating principle
There are three pairs of anti-parallel thyristors connected to the stator of motor. Using
the electric switch feature of the thyristors, the voltage of the motor can be controlled by
changing the triggering angel of the thyristors. The triggering angel of the thyristors is
controlled by microprocessor. So the motor can be started softer and smooth. After the equipment
is up to full voltage, it outputs a bypass signal. User can use this signal to control the bypass
contactor to supply the motor. See figure4-1.

5. Wiring and terminal
5.1 Wiring diagram
Note:
1. There are two wiring ways to control starting and stopping the starter externally. They are three-line and
two-line wiring. (See ①and② in the figure above).Start signal is given by connecting terminal RUN and COM.
Stop signal is given by disconnecting terminal RUN and COM
Connect according the figure①，free stop
Connect according the figure②，soft stop
2. In the SSXA series product, there is no terminals U1,V1,W1.Because there is built-in bypass contactor.
3. In the SSXA series product dose no have the output terminal（K22/K24）.It can be replaced by the programmable
control terminals (K32/K34).The parameter “K3” should be set “bypass”.
4. SSXA series product needs external AC220V power supply. SSXB series product dose not have external AC power
terminals (L/N).
