1. User Manual
Shihlin Electric SS2-TYPE inverters possess many complex parameterized functions that meet most
of the application requirements from the market. But for users who are unfamiliar with inverters,
such a complex inverter may cause confusion. Please read the manual carefully to master the
operation methods of the inverter. In case there is any question, please feel free to contact us.
In Chapter 3 of this manual, all series and the corresponding specifications of Shihlin Electric
SS2-TYPE inverters are listed in detail. Section 3.5 guides the users how to install the inverter and
emphasizes on safety precautions when using the inverter.
Chapter 4 guides the users how to use the inverter. In Section 4.1, the operating mode of the
inverter is outlined and how to use the operation panel is described, and in Section 4.2, simple
operating steps are explained. Chapter 5 explains the functions of each parameter in detail.
Terminologies used in this manual are defined as follows:
1. Output frequency, target frequency, steady output frequency
• The actual output current frequency of the inverter is referred to as the output frequency.
• The frequency set by user (through operation panels, multi-speed terminals, voltage signals or
current signals) is referred to as the target frequency.
• When the motor starts running, the output frequency of the inverter will gradually accelerate to
the target frequency until reaching the target frequency and becoming steady. The output
frequency at this time is referred to as the steady output frequency.
2. More detailed instructions on parameter settings are presented in Chapter 5. Please note that
arbitrary adjustment of the parameters may result in abnormal operations. All parameters can be
reset to their default values by the parameter P.998. For offsetting this parameter, please refer to
P.998 in Chapter 5.
3. The operating 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. Shihlin inverter has totally nine operating modes. Please refer to Section 4.1 for
details.
The operation panel is used for numeric value monitoring, parameter setting and target frequency
setting. Shihlin operation panel has totally five working modes. Please refer to Section 4.1 for
details.
4. The difference between terminal name and function name:
A set of printed letters can be found near the terminals of the control board or the main board.
These letters are used to distinguish each terminal, and thus called ‘terminal name’.
For multi-function control terminal and multi-function output terminal, function names have to be
defined in addition to terminal names. A function name indicates the actual function of the
terminal.
Function name is used to explain the functions of a terminal.

5. The difference between ‘on’ and ‘turn on’:
Both ‘on’ and ‘turn on’ are used for explaining the function for the Multi-function control terminal.
The word ‘on’ is used to describe the state; that is, the external switch of the terminal is in the
closed state.
The word ‘turn on’ is used to describe the action of shutting off the switch from the opened state to
the closed state.

3. Installation and Wiring
3.5.1 Transport
Take the pedestal when carrying and don’t only take the cover or any part of the inverter,
otherwise it may drop down.
3.5.2 Sto kpile
This product before installing must be placed in the packaging. If it is not in use, change the
frequency to meet the company's warranty scope and future maintenance. Pay attention to the
following matters for 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.
3.5.3 EMC Installation instru tions
Inverter is similar to other electrical and electronic equipments. In a power system, an inverter is
the electromagnetic interference source and also 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.

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. he better EMI suppression effect
will be obtained by installing the input reactor recommended by this manual. Increase the ferrite of the
input and output terminals (refer to Section 3.6.5), and at the same time increase the zero-phase
reactor (refer to Section 3.6.5) and 4 turns Hitachi metals nano magnetic ring to reduce the
interference in motor side, then can satisfy the limited value of conduction and radiation that is stated
by the CE.
3. Shielding
Good shielding and grounding can greatly reduce inverter interference and improve the
anti-interference capacity of the inverter. Use the good electricity conducting sheet metal box sealing,
the inverter good contacts to metal and let the sheet metal grounded to satisfy the limits value of
radiation stated by the CE.
Input and output lines used cable with shielding, good grounding and shielding to satisfy the limits
value of radiation stated by the CE.
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 Wave
The leakage current contains leakage current from line to line or over ground. It depends on the
size of distributed capacitance when wiring and carrier frequency of frequency. The higher carrier
frequency, longer the motor cable, and 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 5K carrier frequency.
