Observe the information provided on the switchgear packing and concerning transport and
storage.
Ambient air temperatures
for storage
Permissible ambient air temperatures for storage of the switchgear:
• Switchgear with secondary system: -25 °C to +55 °C (option: -40°C to +70°C) in
accordance with the installed secondary devices
• Switchgear without secondary system: -40 °C to +70 °C
Intermediate storage of
the transport units
Storage in closed rooms
• Intermediate storage is possible in the undamaged original packing including transport base
(all packing types)
Outdoor storage:
• Intermediate storage is possible in the undamaged original packing including transport
base, executed as seaworthy crate, for a maximum of 6 months
• Longer storage time is possible after replacement of the desiccant by expert personnel; to
do this, contact the regional Siemens representative
Requirements on the storage place:
• Ground with adequate load-bearing capacity, solid, even and dry
• Ambient air temperatures always within the limit values for the switchgear
• Protected against mechanical damages, e.g. collision with vehicles, falling objects, tilting,
falling over, vandalism
• Protected against humidity, e.g. rain, flooding, melting water, foam, persistent high air
humidity, floor humidity
• Protected against direct solar radiation
• Protected against corrosive, dust-ridden or arenaceous ambient, and against pollution
• Protected against the wind
• Protected against vermin (e.g. rats, mice, insects), and vegetation overgrowth
Instructions for intermediate storage:
• Do not unpack small parts (to prevent corrosion and loss)
• Check packing for ingress of humidity (condensation) every 4 weeks
