Page 11 of 16 Housed varistors T14 series ThermoFuse varistors Cautions and warnings General 1. EPCOS metal oxide varistors are designed for specific applications and should not be used for purposes not identified in our specifications, application notes and data books unless otherwise agreed with EPCOS during the design-in-phase. 2. Ensure suitability of SIOVs through reliability testing during the design-in phase. SIOVs should be evaluated taking into consideration worst-case conditions. 3. For applications of SIOVs in line-to-ground circuits based on various international and local standards there are restrictions existing or additional safety measures required. Storage 1. Store SIOVs only in original packaging. Do not open the package prior to processing. 2. Storage conditions in original packaging: Storage temperature: 25 °C ... +45 °C, Relative humidity:
