3. Warning
■ Operators
• In order for the SL-C 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-C.
• When performing electrical wiring, always follow electrical standards and regulations for the country or
region in which the SL-C 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-C.
• The SL-C 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-C in the presence of substances, such as heavy smoke, particulate matter, or corro-
sive chemical agents, that may induce deterioration in product quality.
• Install the SL-C 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-C has not undergone the model certification examination in accordance with Article 44-2 of the
Japanese Industrial Safety and Health Law. The SL-C, 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-C is to be installed must be susceptible to an emergency stop at all
operating points during its operation cycle. Do not use the SL-C for machines with irregular stop times.
• Do not use the SL-C for power presses equipped with full-revolution clutches.
• Do not use the SL-C 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-C 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 hazard-
ous zone or hazard, and so implement additional safety measures such as installing safeguards when
there is the possibility of such displacements.
