Hitachi Universal Storage Platform VM Installation Planning Guide
Loudness
The acoustic emission values [loudness in dB(A)] for the Universal Storage
Platform VM storage system are:
• Front/rear = 65 dB(A)
• Both sides = 65 dB(A)
Vibration and Shock
lists the vibration and shock tolerances for the USP VM. The USP
VM can be subjected to vibration and shock up to these limits and still
perform normally. Consider these requirements if there are large generators
located on the floor above or below the storage system. Generators or any
other source of vibration, if not insulated or shock mounted, can cause
excessive vibration that may adversely affect the storage system.

NOTE:
1. The vibration specifications apply to all three axes.
2. See ASTM D999-91, Standard Methods for Vibration Testing of Shipping Containers.
3. See ASTM D4728-01 Test Method for Random Vibration Testing of Shipping
Containers.
4. See ASTM D5277-92, Standard Test Methods for Performing Programmed
Horizontal Impacts Using an Inclined Impact Tester.
5. See ASTM D6055-96, Standard Test Methods for Mechanical Handling of Unitized
Loads and Large Shipping Cases and Crates.
