Preparing a Drive for Storage
Storing an Installed Drive
• To protect it from dust and water droplets, cover the whole drive with two layers of sheeting. The sheet should be at
least 0.1 mm thick.
• Completely seal the bottom of the drive with sealant to prevent moisture and dust from entering the drive.
• Protect every corner of the drive with shock-absorbing materials to prevent the sheet getting broken.
Storage in a Warehouse
Before storing the drive for a long period in a warehouse, carefully read
and the following precautions.
• To protect it from dust and water droplets, cover the whole drive with two layers of sheeting. The sheet should be at
least 0.1 mm thick.
• Protect every corner of the drive with shock-absorbing materials to prevent the sheet getting broken.
• Roll in the sheet under the bottom of the drive so that the drive will not absorb moisture from the floor.
• Do not rest the drive directly on the floor but on 50 to 100 mm square timbers.
Place the timbers as shown in
so that the whole bottom of the drive is evenly loaded.
• Place the drive in the orientation indicated in the dimension drawings. Do not place it on its side or stack drives.
• Adopt measures to prevent the drive getting scratched or damaged by external impacts.
• Insert the silica gel into any drive openings to absorb moisture. As a guide to the appropriate quantity, use 1 kg per
cubic meter.
Replace the silica gel every three months. Note, however, that the period the silica gel remains effective differs
depending on the ambient humidity.
• Provide supports or devise other measures to prevent the drive falling down.
• The drive is not suited to storage outside a warehouse.
