5.8 Intermediate storage of the transport units
• In original packing as far as possible
• Observe permissible storage temperature from −25 °C to +70 °C.
• In a weatherproof place
• Protected against damage
• If packed in seaworthy crates, the switchgear can be stored for a maximum of 6 months (desiccant
bags) at a humidity of max. 60 %
• Store transport units in such a way that they can be taken out later in the correct order for installation.
As a rule, the panels should be stored in a closed room. The storage room must have the following
characteristics:
• Floor with adequate load-bearing capacity (weights as per delivery note)
• Even floor to enable stable storage
• Well-ventilated and as free of dust as possible
• Dry and protected against humidity and vermin (e.g. insects, mice, rats)
• Check humidity in the packing every 4 weeks (condensation)
• Do not unpack small parts to avoid corrosion and loss.
If the switchgear or parts thereof are delivered in seaworthy crates, these can be stored up to 6/12 months in
other rooms or outdoors. The storage location must have the following characteristics:
• Floor with adequate load-bearing capacity (weights as per delivery note)
• Protected against humidity (rain water, flooding, melting water from snow and ice), pollution, vermin
(rats, mice, termites, etc.) and unauthorized access
• Place all crates on planks and square timber for protection against floor humidity
• After 6 months of storage, have the desiccant agent regenerated professionally. To do this, ask for
expert personnel via the regional Siemens representative.
