Precautions Safety Precautions Power Supply Do not impose an excessive voltage on the, otherwise it may be damaged. Do not impose AC current ( to 2 VAC) on any DC model, otherwise it may be damaged. Short-circuit Do not short-circuit the load, or the may be damaged. The s short-circuit protection function will be valid if the polarity of the supply voltage imposed is correct and within the rated voltage range. Wiring Be sure to wire the and load correctly, otherwise it may be damaged. Connection with No Be sure to insert loads when wiring. Make sure to connect a proper load to the in operation, otherwise it may damage internal elements. Do not expose the product to flammable or explosive gases. Do not disassemble, repair, or modify the product. Correct Use Designing Power Reset Time The is ready to operate within ms (6ms for NO+NC -B / -C types) after power is supplied. If power supplies are connected to the and load respectively, be sure to supply power to the before supplying power to the load. Effects of Surrounding Metal When mounting the within a metal panel, ensure that the clearances given in the following table are maintained. l m D d dia. l n m Type Dimension M2 M8 Shielded Nonshielded l (See note.) Short barrel (Unit: mm) M Long barrel (See note 2.) m d D.5 n l 5 22 m d D 5 22 n Note. In the case of using the supplied nuts. If true flash mounting is necessary, apply a free zone of.5 mm. 2. In the case of using the supplied nuts. If true flush mounting is necessary, apply a free zone of mm. D-2

14 Power The may output a pulse signal when it is turned. Therefore, it is recommended that the load be turned before turning the. Power Supply Transformer When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer. Mutual Interference When installing two or more s face-to-face or side-by-side, ensure that the minimum s given in the following table are maintained. Type Dimension M2 M8 Short barrel Shielded A 6 B Periodically perform the following checks to ensure stable operation of the over a long period of time.. Check for mounting position, dislocation, looseness, or distortion of the and s. 2. Check for loose wiring and connections, improper contacts, and line breakage.. Check for attachment or accumulation of metal powder or dust.. Check for abnormal temperature conditions and other environmental conditions. 5. Check for proper lighting of indicators (for models with a set indicator.) Never disassemble or repair the. Environment Water Resistivity The s are tested intensively on water resistance, but in order to ensure maximum performance and life expectancy avoid immersion in water and provide protection from rain or snow. Operating Environment Non-shielded Wiring High-tension Lines (Unit: mm) M Long barrel A 2 2 B 2 2 Wiring through Metal Conduit: If there is a power or high-tension line near the cable of the, wire the cable through an independent metal conduit to prevent against damage or malfunctioning. Mounting The must not be subjected to excessive shock with a hammer when it is installed, otherwise the may be damaged or lose its water-resistivity. Do not tighten the nut with excessive force. A washer must be used with the nut. M2 M8 M Type Torque Nm 7 Nm 8 Nm Maintenance and Inspection Ensure storage and operation of the within the given specifications. Inrush Current A load that has a large inrush current (e.g., a lamp or motor) will damage the, in which case connect the load to the through a relay. <SUITABILITY FOR USE> OMR shall not be responsible for conformity with any standards, codes, or regulations that apply to the combination of the products in the customer s application or use of the products.
