Design Precautions
Install protection circuit on the outside of Products to protect the entire control system when external power
supply or Products have problems.
1. As the malfunction & incorrect result of Products could damage the stability of the entire systems
and human body, You must install damage preventing interlock circuit such as emergency stop,
protective circuits, positioning upper and lower limit switch and interlock for forward/reverse
operation.
2. When computer or other controllers communicate and exchange data with products or change
operation mode of products, set up protective sequence program in PC or Controller for protecting
system from communication error.
3. The output signal or communication lines should be separated from the power line or high tension
wire. They should be installed 100mm(3.94 Inch) or more from each other.
Precautions on wiring
Be sure the wiring is done correctly by checking the product’s rated voltage and the terminal layout. Incorrect
wiring could result in fire, damage or malfunctions.
Tighten the terminal screw with the specified torque. If the screw of terminal are loose, it could result in short
circuit, fire, malfunctions.
The FG Terminal must be used a dedicated ground. Not doing so could result in malfunctions.
1. Grounding should be the Class 3 grounding. The cable for grounding should be more than 2㎟
2. The grounding point be closed to the products and make short the distance to the ground cable if
possible. Please see below.

Precautions on Install
Do not install the location which exceeds allowed temperature. Product can be damaged or shorten the life.
Especially Install environment as below should be avoided.
1. Do not Install product to the place which the ambient temperature is out of limits, from 0℃to 50℃
or on the surface of control board which high pressure equipment is installed.
2. Do not install to the place where strong shock or vibration continuously have impacted on product.
3. The space between back of product and back of control board must be more than 100mm for
maintenance and ventilation.
4. Do not storage and operate in the place in direct sunlight. By the strong ultraviolet rays can
