Guide for Manual
Guide for Manual
The Shihlin electric SE2-TYPE inverters have been designed with many complex parameterized
functions to meet most of the application requirements from the market. For customers who contact
inverters for the first time, such a complex inverter may cause troubles when using it. So the users
are expected to read each part of this manual carefully so as to master the operating method of the
inverter. In case there is any question, please feel free to contact us.
In Chapter 2 of this manual, all the series and the corresponding specifications of Shihlin electric
SE2-TYPE inverters are listed in detail. Section 2-5 guids customers how to install the inverter and
emphasizes on precautions for safety that much attention should be paid to when utilizing the
inverter.
Chapter 3 guides customers how to use the inverter. In Section 3-1, the operating mode of the
inverter is outlined briefly; in Section 3-2, how to use the operation panel is described, and in
Section 3-3, simple operating steps are explained. Chapter 4 explains the functions of each parameter
in detail.
The definitions of terminologies in this manual are as follows:
1. Output frequency, target frequency, steady output frequency
• The actual output current frequency of the inverter is called ‘output frequency’.
• The frequency set by user (through a operation panel, multi-speed terminals, voltage signal or
current signal) is called ‘target frequency’.
• When the motor starts running, the output frequency of the inverter will gradually accelerate to the
target frequency, and finally run steadily at the target frequency. The output frequency at this time
is called ‘steady output frequency’.
2. There are detailed instructions on parameter settings in Chapter 4. In case users 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 P.998. For the setting
procedure of this parameter, please refer to P.998 in Chapter 4.
3. The ‘operation mode’ of inverter, and the ‘working mode’of the operation panel:
The operating mode determines the reference source for the target frequency and the signal source
for starting. The Shihlin inverter has totally 9 operating modes. Please refer to Section 3-1 for
details.
The operation panel mainly concerns monitoring of numeric values, setting of parameters and
setting of target frequency. The Shihlin operation panel has totally 5 working modes. Please refer
to Section 3-2 for details.
4. The difference between ‘terminal name’and ‘function name’:
Near the terminals of the control board or the main board, printed letters can be found. These
letters are used to distinguish each terminal, and thus called ‘terminal name’.
For ‘multi-function control terminal’ and ‘multi-function output terminal’, besides the terminal
name, the ‘function name’ is also necessary to be defined. The function name indicates the actual
functions of the terminal.

Guide for Manual
When explaining the function for a terminal, the name used is its ‘function name’.
5. The difference between ‘on’and ‘turn on’:
When explaining the function for the ‘multi-function control terminal’, two words ‘on’and ‘turn
on’are often used.
The ‘on’is used to indicate that the external switch of the terminal is in close state, and thus
belongs to the description of the state.
The ‘turn on’is employed to describe the action that the external switch of the terminal is shut on
from the open state to the close state, and thus belongs to the description of action.
6.All the ‘P.’s mentioned in this manual mean ‘parameter’.

2.5.3 EMC Installation instructions
Inverter is the same as other electrical and electronic equipment, when working in a power system, it
is the electromagnetic interference sources, and also is the electromagnetic receiver. The working
principle of inverter determines that it will produce certain electromagnetic interference and noise, in
order to guarantee the inverter to the electromagnetic environment in certain work, in designed, it
must have a certain interference of electromagnetic interference ability. In order to make the drive
system can normal operation, and meet the challenge which CE declared, please meet the following
several aspects in installation:
1. Field wiring
Power line from power transformer independent power supply, generally uses five core or four core,
forbidden neutral and ground share a thread.

13
2.Introduction of Shihlin Inverter
Introduction of Inverter
Commonly signal wire (weak) and power lines (heavy) are in control cabinet, to inverterr, electric
line of force divided into incoming lines and tail wire. In wiring, signal wire and power lines should
distributed in different regions, in close (within 20cm), parallel lines and interlace lines are
unallowed strictly, and the two cannot be tied together. If the signal cable must pass through between
power lines, the two should maintain a 90 degree Angle. The parallel lines and interlace lines which
of power line can not crisscross wiring or be tied together, especially in occasions which noise filter
installed, it will make coupled noise when the electromagnetic noise through the distributed
capacitance, thus noise filter will out of action.
Generally the same controller with different electric equipment, such as inverter, filter, PLC,
measurement instrument, its transmitter electromagnetic noise to external and bear ability each are
not identical, this requires to classify these equipments, the classification can be divided into strong
noise quipment, and noise sensitive equipment, the similar equipmentmust be installation in the same
area, inhomogeneity equipment must be keep distance more than 20cm.
2. Input noise filter, input and output magnet ring (zero phase reactor)
Increase noise filter in the input terminal, which will isolate the inverter and the other equipment can
effectively reduce the conduction and radiation ability. Install the input reactor this synopsis
recommendation, can satisfy the limits value of conduction and radiation which CE declared. In the
input and output terminal increased the ferrite lateral auxiliary will be better effect.
3. Shield
Good shielding and grounding can greatly reduce the interference of inverter, and can improve the
anti-interference ability of the inverter. Using the good conduct electricity sheet metal sealing, and let
the sheet metal grounding, can satisfy the limits value of radiation which CE declared.
4. Grounding
Inverter at work must be safe and reliable grounding. Grounding is not only for equipment and safety,
but also is the simplest, the most efficient and the lowest cost method to solving the EMC problem,
should be prioritized. Please refer to the "terminal wiring" section.
5. Carrie Wave
The leakage current contains the leakage current from line to line or over the ground. It depends on
the size of the capacitance and the carrier frequency of the wiring system. The carrier frequency is
higher, the motor cable is longer, the cable cross-sectional area is larger, and the leakage current is
larger too. Reduce the carrier frequency can effectively reduce the leakage current, when a long line
of motor (50m above), the output side should be installed ac reactor or sine wave filter, when the
motor line is longer, every distance should to install a reactor.At the same time, reduce carrier
frequency can effectively reduce the conduction and radiation interference, in 2K carrier frequency,
can satisfy the limits value of the conduction and radiation which CE declared.

No matter what kind of multi-function control terminal it is, all of its outside wire arrangement can be
considered as a simple switch. If the switch is ‘on’, the control signal will be put into the terminal, if the
switch is ‘off’, the control signal is shut off.
If ‘Sink Input’ mode is selected, the function of the terminal is active when it is shorted with SD or
connected with the external PLC. In this mode, the current flows out of the corresponding terminal
when it is ‘on’
. Terminal SD is common to the contact input signals. When using an external power
supply for transistor, please use terminal PC as a common to prevent misoperation caused by leakage
current.

Introduction of Inverter
Note: 1. For SE2-0XX-0.4K~11K (0.5HP~15HP) series of inverters, the brake resistor isn’t appended when sales.
2. For the related knowledge on regenerative voltage, please refer to P.30 in Chapter 4.
3. P and N are the positive and negative terminals of the internal DC voltage of the inverter. In order to
strengthen the braking capability during deceleration, it is suggested to purchase the option of ‘brake unit’
which is mounted between the terminals P and N. The ‘brake unit’ can effectively dissipate the feedback
energy from the motor to the inverter when decelerating. In case there is any problem on purchasing of
the ‘brake unit’, please feel free to contact us.
4. For safety and reduce noise, grounding terminals of inverter must to be good grounded. To avoid electric
shocks and fire accident, external metal wire of electrical equipment should be short and thick and it
should be connected to the special grounding terminals of inverter. If many of the inverters are placed
together, all inverters must be connected to the common ground. Please refer to the following picture
and
determine not formed circuit between grounding terminal.
