• The GS (Non-contact) can only be used in combination with dedicated actuators. It cannot be used in combination with other actuators or similar devices.

• Do not bypass the GS (Non-contact), remove it or change its installation orientation after installation.

• Do not use a replacement actuator to bypass the GS (Noncontact). Store replacement actuators strictly to prevent their easy access.

• When using the GS (Non-contact) to protect machine operators against a hazard or hazardous zone or when using the GS (Non-contact) as a safety component for any purpose, always follow the applicable requirements of the laws, rules, regulations and standards in the country or region where the GS (Non-contact) is used. For such regulations, you should directly contact the regulatory agency responsible for occupational safety and health in your country or region.

• Depending on the type of machine on which the GS (Noncontact) is installed, there may be special safety regulations related to the use, installation, maintenance, and operation of the safety component. In such a case, you must fulfill such safety regulations. The responsible personnel must install the GS (Non-contact) in strict compliance with such safety regulations.

• The responsible personnel must do the training to the assigned personnel for the correct use, installation, maintenance, and operation of the GS (Non-contact).

• The user of the machine must receive specialized training related to the GS (Non-contact), and must then understand and adhere to the safety restrictions, laws, and regulations in the country or area in which the GS (Non-contact) is being used.

• If the GS (Non-contact) does not operate correctly, the user of the machine must report this information to the party responsible for the use of the GS (Non-contact) and immediately stop the machine.

 Environment of use

• Do not use the GS (Non-contact) in an environment (temperature, humidity, interfering light, etc.) that does not conform to the specifications contained in this manual.

• Do not use a device that emits strong electromagnetic waves near the GS (Non-contact).

• This product is not intended for use as an explosion-proof product. Do not use this product in a hazardous location and/or potentially explosive atmosphere.

• Do not use the GS (Non-contact) in the presence of substances, such as heavy smoke, particulate matter, or corrosive chemical agents, that may induce deterioration in product quality.

• Indoor use only.

 Target machines for installation

• It must be possible to perform an emergency stop on the machine to which the GS (Non-contact) is installed at any and all operation points during the operation cycle. Also, do not use the GS (Non-contact) on machines that have irregular stop times.

• Do not use the GS (Non-contact) to control (stop forward motion, etc.) trains, cars and other transportation vehicles, aircraft, equipment for use in space, medical devices, or nuclear power generation systems.

 Circuit design and wiring

• Be sure to turn the power supply off before performing electrical wiring.

• Perform electrical wiring according to the electrical conventions, restrictions, standards, and laws in the country or area in which the GS (Non-contact) will be used.

• Use cables with length less than or equal to the specification in this manual. Usage of cables longer than the specified value may cause the improper operation of safety functions and may cause a dangerous situation.
