10 / 13 page G3PF 10 Safety Precautions Refer to Safety Precautions for All Solid State Relays. The G3PF may rupture if short-circuit current flows. As protection against accidents due to short-circuiting, be sure to install protective devices, such as fuses and no-fuse breakers, on the power supply side. Minor burns may occasionally occur. Do not touch the SSR or the heat sink while the power is being supplied or immediately after the power supply has been turned OFF. The SSR and heat sink become extremely hot. Minor electrical shock may occasionally occur. Do not touch the main circuit terminals on the SSR immediately after the power supply has been turned OFF. Shock may result due to the electrical charge stored in the built-in snubber circuit. Minor electrical shock may occasionally occur. Always turn OFF the power supply before performing wiring. Also, always attach the cover terminal. OMRON constantly strives to improve quality and reliability. SSRs, however, use semiconductors, and semiconductors may commonly malfunction or fail. In particular, it may not be possible to ensure safety if the SSRs are used outside the rated ranges. Therefore, always use the SSRs within the ratings. When using an SSR, always design the system to ensure safety and prevent human accidents, fires, and social harm in the event of SSR failure. System design must include measures such as system redundancy, measures to prevent fires from spreading, and designs to prevent malfunction. (1) Operating and Storage Environments Do not use or store the G3PF in the following locations. Doing so may result in damage, malfunction, or deterioration of performance characteristics. 1. Locations subject to corrosive or flammable gases. 2. Do not store in locations subject to ambient storage temperatures outside the range −30 to 70°C. 3. Do not use in locations subject to ambient operating temperatures outside the range −20 to 60°C. 4. Do not use in locations subject to relative humidity outside the range 25% to 85%. 5. Locations subject to high temperature or high humidity. 6. Locations subject to condensation as the result of rapid changes in temperature. 7. Locations subject to exposure to water, oil, or chemicals. 8. Locations subject to dust (especially iron dust) or salts. 9. Locations subject to rainwater or water splashes. 10.Locations subject to direct sunlight. 11.Locations subject to shock or vibration. (2) Transport Do not transport the G3PF under the following conditions. Doing so may result in damage, malfunction, or deterioration of performance characteristics. 1. Conditions in which the G3PF may be subject to water or oil splashes. 2. Conditions in which the G3PF may be subject to high temperature or high humidity. 3. Conditions in which the G3PF may be subject to condensation as the result of rapid changes in temperature. 4. Conditions in which the G3PF may be dropped or subject to excessive vibration or shock. 5. Conditions in which the G3PF is not packaged. (3) Mounting 1. Do not use the G3PF if the heat radiation fins have been bent by being dropped. Doing so may result in malfunction due to a reduction in the heat radiation performance. 2. Do not block the movement of the air surrounding the SSR or heat sink. Abnormal heating of the SSR may result in shorting failures of the output elements or burn damage. 3. Make sure that there is no excess ambient temperature rise due to the heat generation of the G3PF. If the G3PF is mounted inside a panel, install a fan so that the interior of the panel is fully ventilated. Otherwise, shorting failures of the output elements or burn damage may result. 4. Make sure the DIN track is securely mounted. Otherwise, the G3PF may fall. 5. Do not handle the G3PF with oily or dusty (especially iron dust) hands. Doing so may result in malfunction. 6. Mount the G3PF in the specified direction (on a vertical or horizontal surface). Otherwise excessive heat generated by the G3PF may cause short-circuit failures of the output elements or burn damage. 7. When mounting the G3PF to a control panel or other fixture with screws, be sure to tighten the screws to a torque of 0.98 to 1.47 N·m. A lower level of tightening torque may cause the G3PF to fall. 8. Do not drop the G3PF or subject it to excessive vibration or shock. Doing so may result in damage, malfunction, or deterioration of performance characteristics. (4) Wiring 1. Use wires that are thick enough for the load current. Otherwise, excessive heat generated by the wire may cause burning. Tightening torque M2: 0.22 to 0.28 N·m M3: 0.4 to 0.56 N·m M5: 1.57 to 2.35 N·m Control connector mounting torque (detachable terminal) 0.25 to 0.3 N·m 2. When tightening terminal screws, prevent any non- conducting material from becoming caught between the screws and the tightening surface. Otherwise, excessive heat generated by the terminal may cause burning. 3. Use wires that are suited to the load current and voltage. Otherwise, excessive heat generated by the wires may cause burning, or the outer covering of the wire may melt, resulting in electrical shock or ground fault. 4. Use a crimp terminal size that is suited to the diameter of the wire. Otherwise, it may result in burning, or the outer covering of the wire may melt, resulting in electrical shock or ground fault.
