Thank you for choosing Shihlin SS2 series AC Drive.
The instruction will describe on the use and points for attention of products. Before installing, please be sure to carefully read the
Instruction, so that the inverter can be used in proper and safe way.
1) 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. Even if power supply was cut off, residual voltage is

in the internal capacitor. After the power cut off, waiting time should be no shorter than the time in inverter logo.
The inverter must be connected to the ground properly.

 Do not operate or touch the radiator 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
The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise burst, damage, etc. may occur.

 Don't conduct a pressure test on components inside inverter, for semiconductor of inverter is easily to be broke down and damaged by high voltage.
While power is ON or for some time after power-OFF, do not touch the inverter as it will be extremely hot. Touching these devices may cause a burn.

The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.

 The polarity (+ and -) must be correct. Otherwise burst, damage, etc. may occur.
Inverter must be installed on a nonflammable wall without holes (so that nobody touches the inverter heat sink on the rear side, etc.). Mounting it to

or near flammable material may cause a fire.
If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current may cause a fire.

Note1: When mounting inverters of different sizes in parallel, please align the clearance below each inverter to install, which is easy to change the cooling
fan.
Note2: When it is inevitable to arrange inverters vertically to minimize space，take such measures as to provide guides since heat from the bottom
inverters can increase the temperatures in the top inverters, causing inverter failures.

 Wiring method
Power supply connection

For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off the sheath of
the wire and apply directly.
Insert the blade terminal or the single wire into a socket of the terminal.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with neighboring
wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.
7mm
(2) Crimp the blade terminal.
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is inappropriate, or the

Note1: Please Use a small flat head screw driver (tip thickness: 0.6 mm, width: 3.0mm). If a flat head screw driver with a narrow tip is used, terminal
block may be damaged.

Note2: Tightening torque is 3.2~4.8kgf.cm, too large tightening torque can cause screw slip, too little tightening torque can cause a short circuit or
malfunction.

 Wiring Precautions
12 12 12
After wiring, wire offcuts must not be left in the inverter.

12 12 12
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
14 14 14 When drilling holes in a controller, please take caution not to allow chip powder to enter the inverter.
To prevent a malfunction due to noise, keep the signal cables 10 cm (3.94 inches) or more away from the power cables. Also,

14 14 14
Separate the main circuit cables at the input side from the main circuit cables at the output side.
12 12 12
Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.
