Siemens SIMOTICS XP Operating Instructions Manual page 39

Choose a dry storage location which is safe from flooding and free from vibration. Repair any
damage to the packaging before putting the equipment into storage if this is necessary to
ensure proper storage conditions. In order to ensure protection against ground moisture,
locate machines, equipment and crates on pallets, wooden beams or foundations. Prevent
equipment from sinking into the ground. Do not impede air circulation under the stored
items.
Covers or tarpaulins used to protect the equipment against the weather must not come into
contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air
can circulate freely around the equipment.
Storing indoors
The storage rooms must provide protection against extreme weather conditions. They must
be dry, free from dust, frost and vibration and well ventilated.
Bare metal surfaces
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be
coated with an anti-corrosion agent which will last for a limited amount of time (<6 months).
Apply suitable anti-corrosion measures for longer storage times.
The materials used are specially designed for the temperature range required by the
customer. The relevant temperature limits are specified on the rating plate.
Risk of explosion due to damaged sealing materials
Storing the machine at temperatures that do not fall within the specified limits can damage
the material of the seals and cause them to fail. As a result, a potentially explosive gaseous
atmosphere can enter the machine and be ignited during commissioning. Explosions can
occur. This can result in death, serious injury or material damage.
• Do not store the machine in conditions that lie outside the specified temperature limits.
Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For machines that have a special design regarding the ambient temperature in the operating
state or the installation altitude, other conditions could apply regarding the storage
temperature. In this case, refer to the machine rating plate for data on the ambient
temperature and installation altitude.
Storage time
Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce
the useful life of the bearing grease (aging).
