1.1 Safety instructions
Thank you for choosing Shihlin inverters SA3 series. This user manual introduces how to use the product correctly.
Please read the user manual carefully before using the product. In addition, please use the product after understanding
the safety instructions.
Safety Instructions
Installation, operation, maintenance and inspection must be performed by qualified personnel.
In this instruction, the safety instruction levels are classified into "Warning" and "Caution".
Warning: Incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Caution: Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause
only material damage.
Warning
While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover
or the wiring cover removed. Otherwise you may access the exposed high voltage terminals or the charging part of the
circuitry and get an electric shock.
It is crucial to turn off the motor drive power before any wiring installation or inspection is made. Before the inverter
CHARGE light is OFF, which indicates that there is still high voltage in it, please do not touch the internal circuit and
components. Operation must be made after measuring the voltage which is less than 24 VDC between /P and/N and
with avometer.
The inverter must be connected to the ground properly.
Do not operate or touch the heat sink or handle the cables with wet hands. Otherwise you may get an electric shock.
Do not change the cooling fan while power is ON. It is dangerous to change the cooling fan while power is ON.
Caution
Voltage applied to each terminal must be the one specified in the user manual; otherwise, failure or damage may be caused.
Do not operate a voltage-resistant test for the parts inside the inverter because semiconductors in inverter may be easily
damaged due to high-voltage breakdown.
Do not touch the inverter because the temperature of the inverter is very high when it is powered on or right after
disconnecting the power supply; otherwise, burn may occur.
Failure or damage may be caused due to wrong wiring.
Do not reverse the polarities (+, -) by mistake, failure or damage may be caused.
Please install the inverter on nonflammable walls without holes (to avoid contacts with the cooling fin of the inverter from
the back). If the inverter is installed on or close to flammable objects it may cause a fire.
Please disconnect the inverter from power supply in case of failure. Overload current passes through the inverter
continuously may cause a fire.
Do not connect a resistor on DC terminals +/P and -/N directly; otherwise it may cause fire.
Other Precautions:
*1 If the product is ultimately used as a military unit, or when the product is used for weapons manufacturing, etc., this
product will be included in the export product control object specified in the “Foreign Trade Law of the PRC”. When
exporting, strict inspection and export procedures are required.
*2 In this manual, the case or the safety cover will be removed, and the description will be made in graphics and text in
order to explain the product in detail. When operating, to ensure safety be sure to install the case and wire correctly
according to the regulations referred in the manual.
*3 Graphics in the manual are slightly different from the actual product for the convenience of illustrating, which will not
affect customer rights.
*4 To improve our products, parameters and contents may be modified in the future, and the contents of this manual are
subject to change without notice. Please download the latest version from Shihlin website(www.sseec.com.cn or

Definitions of terminologies
MANUAL GUIDE 15
1.3 Definitions of terminologies
Output frequency, target frequency, steady output frequency
The actual output current frequency of inverter is called “output frequency.”
The frequency set by user (via keypad, multi-speed terminals, voltage signal, and current signal or
communication settings) is called “target frequency.”
When motor starts running, inverter output frequency will gradually accelerate to target frequency before it
finally runs steadily at the target frequency. This output frequency is called “steady output frequency.”
Parameter settings
Detail explanation on parameter settings are provided in Chapter 5. For users who are not familiar with these
settings, arbitrary adjustment of the parameter may result in abnormal operations. All parameters can be
reset to their default values by the parameter of 00-02. For setting procedures of this parameter, please refer
to 00-02 in Section 5.1.2
The “operation mode” of the inverter and “working mode” of the keypad
Target frequency command source and start signal source depend on inverter operation mode. There are
nine operating modes in Shihlin inverter. Please refer to Section 4.3 for details.
The keypad is used mainly for monitoring the numeric values, setting parameters and target frequency. There
are 4 working modes on the Shihlin inverter’s keypad. Please refer to Section 4.2 for details.
The difference between “terminal name” and “function name”:
Printed letters can be found near the terminals on control board and main board. They are used to distinguish
each terminal and are called “terminal name.”
For “multi-function control terminal” and “multi-function output terminal,” besides the terminal name, it is also
necessary to define the “function name.” The function name indicates the actual functions of the terminal..
When explaining the function for a terminal, the name used is its “function name”
The difference between “on” and “turn on”:
When describing the function for the “multi-function digital input terminal”, two words “on” and “turn on” are
often used:
The word “on” is used to indicate that the external switch of the terminal is in close state, and thus it belongs
to the description of the state.
The word “turn on” is used to describe the action that the external switch of the terminal is shut from the open
state to the close state, and thus belongs to the description of action. Similarly, the words “off” and “turn off"
belong to the above-mentioned states and actions.

Note 1: The value indicates the current at rated output. The rated input current value is not only affected by power
transformer, input side reactor, wiring condition, but also fluctuates with the impedance of the power supply side.
Note: The test conditions for rated output current, rated output capacity, inverter power consumption are: carrier
frequency 00-11(P.72) set default; inverter output voltage 440V; output frequency 60Hz, ambient temperature
40℃.
