Certification to the IEEE 693 – Level: High standard demonstrates that the Energy Center can withstand acceleration up to 2. 5 times the force of gravity and be relied upon to provide power during major seismic events. The use of seismic-rated enclosures is recommended in areas where earthquake activity is possible. In addition, power plants, railroads, airports and other installations use rack-mounted electrical and electronic equipment that is subjected to vibration and other motion which may over-stress. Whether your venue is earthquake-prone or subject to regular vibration, such as an airport or factory, a seismic enclosure may be the answer for keeping equipment safe. Eaton Seismic Cabinets are performance-tested to EIA-310-E, Seismic Zone 4 (NEBS GR-63-CORE) standards. Seismic enclosures. This white paper outlines various standards related to electrical infrastructure and details the methods used to test and certify nVent HOFFMAN enclosures for earthquake resistance.
