Outdoor storage
Regenerating the
seaworthy packing
52/214
The following switchgear parts must be stored in closed rooms:
• Unpacked parts
• Transport units which are not packed in seaworthy crates
The storage room should have the following characteristics:
• Well-ventilated
• Free of dust
• Dry and protected against flooding
• The relative humidity should not exceed 50%
• Protected against vermin (e.g. insects, mice, rats)
• Even floor to enable stable storage
• Floor with adequate load-bearing capacity
• Sufficient size to enable clearly arranged storage
➭ Do not unpack small parts to avoid corrosion and loss.
➭ Store transport units in such a way that they can be taken out later in the correct order for
installation.
➭ Provide for sufficient ventilation in heated storage rooms.
➭ Check transport units for condensation every 4 weeks.
➭ If the inside of the packing or parts of the switchgear show condensation:
Remove the packing, dry the switchgear and the packing. Then, re-pack the switchgear.
The storage place must have the following characteristics:
• Protected against rain water
• Protected against flooding as well as melting water from snow and ice
• Protected against pollution and vermin (e.g., insects, mice, rats)
• Even floor to enable stable storage
• Floor with adequate load-bearing capacity
• Sufficient size to enable clearly arranged storage
➭ Place transport units on planks or square timber for protection against floor humidity.
➭ Store transport units in such a way that they can be taken out later in the correct order for
installation.
➭ After 6 months (12 months with seaworthy long-time packing) of storage, unpack the
transport units and store them in closed rooms, or regenerate the seaworthy packing
(see below).
After 6 months (12 months with seaworthy long-time packing) of storage, the protection of
the seaworthy packing is exhausted. If the transport units still need to be stored outdoors,
the seaworthy packing must be regenerated.
➭ If there is no sufficient knowledge about professional regeneration of the packing:
Ask for expert personnel via the competent Siemens representative.
➭ Open the packings.
➭ Replace the desiccant bags by the same number of new desiccant bags.
➭ Pack the switchgear so as to reach full protection:
Heat-seal the PE films hermetically tight and rebuild the seaworthy crates completely.
