User manual OMRON G3NA

[. . . ] Solid State Relays G3NA The reliable choice for Hockey-puck-style Solid State Relays. Available in a Wide Range of Currents. · All models feature the same compact dimensions to provide a uniform mounting pitch. · Built-in varistor effectively absorbs external surges. · Operation indicator enables monitoring operation. [. . . ] Do Not Touch Fan Blades When the fan is operating, do not touch the fan blades with any part of your body or allow foreign matter to come into contact with the blades. Always attach the enclosed finger guard when using the G3NA. Operating Conditions · Only use the G3NA with loads that are within the rated values. Using the G3NA with loads outside the rated values may result in malfunction, damage, or burning. · Use a power supply within the rated frequency range. Using a power supply outside the rated frequency range may result in malfunction, damage, or burning. Do not transport the G3NA under the following conditions. · Conditions under which the G3NA will be exposed to water · High temperatures or high humidity · Without proper packing Precautions for Safe Use Although OMRON continuously strives to improve the quality and reliability of our relays, the G3NA contains semiconductors, which are generally prone to occasional malfunction and failure. Maintaining safety is particularly difficult if a relay is used outside of its ratings. Always use the G3NA within the rated values. When using the G3NA, always design the system to ensure safety and prevent human accidents, fires, and social damage even in the event of G3NA failure, including system redundancy, measures to prevent fires from spreading, and designs to prevent malfunction. G3NA malfunction or fire damage may occasionally occur. Do not apply excessive voltage or current to the G3NA terminals. Heat Dissipation · Do not obstruct the airflow to the G3NA or heat sink. Heat generated from an G3NA error may occasionally cause the output element to short, or cause fire damage. · Be sure to prevent the ambient temperature from rising due to the heat radiation of the G3NA. If the G3NA is mounted inside a panel, install a fan so that the interior of the panel is fully ventilated. · Mount the G3NA in the specified orientation. If the G3NA is mounted in any other orientation, abnormal heat generation may cause output elements to short or may cause burning. · Do not use the G3NA if the heat sink fins are bent, e. g. , as the result of dropping the G3NA. Heat dissipation characteristics will be reduced, possibly causing G3NA failure. · Apply a thin layer of Toshiba Silicone's YG6260 or Sinetsu Silicone's G746, or a similar product to the heat sink before mounting · If a material with high thermal resistance, such as wood, is used, heat generated by the G3NA may occasionally cause fire or burning. [. . . ] These may cause G3NA failure. Leakage current Varistor 4. Do Not Drop Be careful not to drop a Relay or Heat Sink onto any part of your body while working. This is particularly true for the High-capacity Heat Sink (Y92B-P250NF), which weighs 2. 5 kg. 14 Solid State Relays G3NA Solid State Relays G3NA 15 Warranty and Application Considerations Read and Understand this Catalog Please read and understand this catalog before purchasing the products.
