Notes:
1. Environmental specification for operating condition should be satisfied before the storage system
is powered on. Maximum temperature of 32°C should be strictly satisfied at air inlet portion.
2. Recommended temperature range is 21 to 24°C
3. Non-operating condition includes both packing and unpacking conditions unless otherwise
specified.
4. On shipping/storage condition, the product should be packed with factory packing
5. No condensation in and around the drive should be observed under any conditions. No condensation
in and around the drive should be observed under any conditions.
6. The above specifications of vibration are applied to all three axes
7. See ASTM D999-01 The Methods for Vibration Testing of Shipping Containers.
8. See ASTM D5277-92 Test Method for Performing Programmed Horizontal Impacts Using an Inclined
Impact Tester.
9. See ASTM D6055-96 Test Methods for Mechanical Handling of Unitized Loads and Large Shipping
Cases and Crates.
10. Time is 5 seconds or less in case of the testing with device resonance point (6 to 7Hz.
11. When flash modules are installed in the system
