3. Warning
■ Operators
• In order for the SL-CHS to operate properly, the responsible personnel and machine operators must
follow all procedures described in this instruction manual.
• No person other than the responsible personnel and machine operators should be allowed to install or
test the SL-CHS.
• When performing electrical wiring, always follow electrical standards and regulations for the country or
region in which the SL-CHS is being used.
■ Usage environment
• Do not use the device in an environment (temperature, humidity, interfering light, etc.) that does not
conform to the specifications contained in this instruction manual.
• Do not use wireless devices such as cellular phones or transceivers in the vicinity of the SL-CHS.
• The SL-CHS is not designed to be explosion-proof. Never use it in the presence of flammable or
explosive gases or elements.
• Do not use the SL-CHS in the presence of substances, such as heavy smoke, particulate matter, or
corrosive chemical agents, that may induce deterioration in product quality.
• Install the SL-CHS in such a way so that no direct or indirect light from inverter-type fluorescent lights
(rapid-start type lights, high-frequency operation type lights, etc.) shine on the device.
■ Target machine
• The SL-CHS has not undergone the model certification examination in accordance with Article 44-2 of
the Japanese Industrial Safety and Health Law. The SL-CHS, therefore, cannot be used in Japan as a
“Safety Device for Press and Shearing machines” as established in Article 42 of that law.
• The machine on which the SL-CHS is to be installed must be susceptible to an emergency stop at all
operating points during its operation cycle. Do not use the SL-CHS for machines with irregular stop
times.
• Do not use the SL-CHS for power presses equipped with full-revolution clutches.
• Do not use the SL-CHS 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.
• The SL-CHS is designed to protect people or objects from entering a machine's hazardous zone or
hazard. It cannot provide protection against objects or materials that are displaced from the machine's
hazardous zone or hazard, and so implement additional safety measures such as installing safeguards
when there is the possibility of such displacements.
