User manual OMRON G3PE

[. . . ] New Product Solid State Relays for Heaters Single-phase G3PE Compact, Slim-profile SSRs with Heat Sinks. Models with No Zero Cross for a Wide Range of Applications. · RoHS compliant. · Models also available with no zero cross · Improved surge dielectric strength for output circuits. · Mount to DIN Track or with screws. [. . . ] 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. 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. Installation and Handling · Do not block the movement of the air surrounding the G3PE or heat sink. Abnormal heating of the G3PE may result in shorting failures of the output elements or burn damage. · Do not use the G3PE 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. · Do not handle the G3PE with oily or dusty (especially iron dust) hands. · Attach a heat sink or radiator when using an SSR. Not doing so may result in malfunction due to a reduction in the heat radiation performance. Installation and Mounting · Mount the G3PE in the specified direction. Otherwise excessive heat generated by the G3PE may cause short-circuit failures of the output elements or burn damage. · Make sure that there is no excess ambient temperature rise due to the heat generation of the G3PE. If the G3PE is mounted inside a panel, install a fan so that the interior of the panel is fully ventilated. · Make sure the DIN track is securely mounted. · When mounting the heat sink, do not allow any foreign matter between the heat sink and the mounting surface. Foreign matter may cause malfunction due to a reduction in the heat radiation performance. · If the G3PE is mounted directly in a control panel, use aluminum, steel plating, or similar material with a low heat resistance as a substitute for a heat sink. Using the G3PE mounted in wood or other material with a high heat resistance may result in fire or burning due to heat generated by the G3PE. Precautions for Safe Use 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. [. . . ] Size of fans: 92 mm × 92 mm, Air volume: 0. 7 m3/min, Ambient temperature of control panel: 30°C 2. If there are other instruments that generate heat in the control panel in addition to SSRs, more ventilation will be required. Ambient temperature: The temperature that will allow the SSR to cool by convection or other means. 21 G3PE Warranty and Application Considerations Read and Understand this Catalog Please read and understand this catalog before purchasing the products.
