3. On shipping/storage condition, the product should be packed with factory packing.
4. No condensation in and around the drive should be observed under any conditions.
5. The specifications apply to all three axes.
6. See ASTM D999-86, Standard Methods for Vibration Testing of Shipping Containers.
