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 an 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 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
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 of the ‘multi-function control terminal’, the word ‘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’.

2.5.1 Transport
Take the pedestal when carrying and don’t only take the cover or any part of the inverter,
otherwise it may drop down.
2.5.2 Stockpile
This product before installing must be placed in the packaging, if not use, in order to meet the
company's warranty scope and future maintenance, you must pay attention to the following matters
when storage:
1. Must be placed in dry and without dirt place.
2. The environment temperature for storage position must range from -20℃to +65℃.
3. The relative humidity for storage position must range from 0% to 95%, and no condensation.
4. Avoid storing in the environment which contains corrosion gas or liquid.
5. It had better be packed properly and kept on shelf or table.
Note: 1. Even if the humidity meets the standard requirements, icing and condensation can also occur when the
temperature changes rapidly. And the place should avoid.
2. Don't place it on the ground, and it should be placed on appropriate shelf. If in the bad surroundings, the
desiccant should be placed in the packaging bag.
3. If the custody period is more than 3 months, the ambient temperature should not be higher than 30℃. It is
to consider that the character will easily degrade in high temperature when the electrolytic capacitors are
deposited without electricity.
4. If the inverter is installed in device or control board when not in use (especially in construction site or the
humid and dusty place), the inverter should be removed and put in suitable environment according with
the above storage conditions.
5. If the electrolytic capacitors are long-term no electricity, the character will degrade. Do not place it in the
state of no electricity for more than one year.
2.5.3 EMC Installation instructions
Inverter is the same as other electrical and electronic equipment, when working in a distribution
system, it is both the electromagnetic interference sources and the electromagnetic receiver. The
working principle of inverter determines that it will produce certain electromagnetic interference
noise. In order to guarantee the inverter working reliably in the electromagnetic environment, it must
have a certain abilitily of anti-electromagnetic interference in design. In order to make the drive
system work normaly, and meet CE declared requirements, please meet the following several aspects
requirements in installation:
1. Field wiring
Power line supply electric independently from power transformer, five core or four core line are
generally used, null line and ground sharing a single line is forbidden.

2.Introduction of Shihlin Inverter
Introduction of Inverter
Commonly signal wire (weak) and power wire (heavy) are in control cabinet, for the inverter,
power wire is divided into input line and output line. Signal wire is easily interfered by power wire, so that
causing the misoperation of the device. When wiring, signal wire and power wire should be distributed in
different areas, parallel lines and interlaced lines are forbidden at close range(within 20cm), and
especially don’t bundle up the two lines. If the signal cables must pass through the power lines, the
two should keep 90 degree Angle. Interlace lines and banding together is also forbidden for the input
and output line of power wire, especially on the occasions which noise filter is installed. It will cause
the coupling of electromagnetic noise through the distributed capacitance of the input and output
lines, thus the noise filter will out of action.
Generally a control cabinet has different electric equipments such as inverter, filter, PLC,
measurement instrument, their ability of emitting and bearing electromagnetic noise are diverse from
each other, and this requires classifing these equipments. The classification can be divided into
strong noise equipment and noise sensitive equipment, Install the similar equipments in the same area
and, and keep a distance more than 20cm among inhomogeneous equipments.
2. Input noise filter, input and output magnet ring (zero phase reactor)
Adding noise filter to the input terminal, the inverter will be isolated from the other equipments,
and its ability of conduction and radiation will be reduced effectively. The better EMI suppression effect
will be obtained by installing the input reactor recommended by this manual. By adding winding ferrite
bead to the input and output terminal and coordinating with internal filter, the inverters will meet the
CE declared and have a better effect.
3. Shielding
Good shielding and grounding can greatly reduce the interference of inverter, and can improve
the anti-interference ability of the inverter. Sealing off the inverter with the good conductive sheet
metal and connecting the sheet metal to ground, the limit value of radiation which CE declared will
be met.
4. Grounding
The inverter must be connected to the ground safely and reliably. Grounding is not only for
equipment and personal safety, but also the simplest, the most efficient and the lowest cost method to
solving the EMC problem, so it should be prioritized. Please refer to the section of "terminal wiring".
5. Carrier
The leakage current contains the leakage current from line to line or over the ground. It depends
on the size of the distributed capacitance when wiring and the carrier frequency of the frequency. The
higher the carrier frequency, the longer the motor cable, and the larger the cable cross-sectional area
is, the larger the leakage current is. Reducing the carrier frequency can effectively reduce the leakage
current. When the motor line is long (50m above), the output side should be installed with ac reactor
or sine wave filter, when the motor line is longer, a reactor should be installed every other distance.
At the same time, reducing carrier frequency can effectively reduce the conduction and radiation
interference, and the limits value of the conduction and radiation which CE declared can be met in
2K carrier frequency.

Note: 1. For the multi-function control terminals, please refer to P.80~P.84, P.86, and for the multi-function output
terminals, please refer to P.40 in Chapter 4.
2. For SE2-0XX-0.4K~11K (0.5HP~15HP) series, the multi-function control terminals can select the ‘Sink
Input’ mode or the ‘Source Input’ mode by the jumper. When the Jumper is on the left side, ‘Sink Input’
mode is chosen, and ‘Source Input’ mode is chosen when on the right side. Shown as follows:
Sink Input Source Input
No matter what kind of multi-function control terminal 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 output transistor, please use terminal PC as a common to prevent misoperation caused by
leakage current.
