24
ATTENTION!
Supplied desiccant bags lose their effectiveness if they are not stored in the undamaged
original packing.
Do not damage or remove packing of desiccant bags.
Do not unpack desiccant bags before use.
If the comprehensive accessories, the delivered switchgear or parts thereof have to be stored
before installation, a suitable storage room or place has to be selected and prepared.
In a suitable storage room, condensation must not be possible; if necessary, cooling or
heating systems should be installed to prevent condensation.
Intermediate storage of the transport units:
• In original packing as far as possible
• Observe the permissible storage temperature from -25 °C to +70 °C in accordance with
the installed secondary devices. In the individual case, the electronic components must
be checked regarding the permissible limit temperatures and the relevant temperatures
for the application (e.g. Siemens Siprotec in the range 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) with a relative humidity of 60 %.
• Store transport units in such a way that the can be taken out later in the correct
order for installation.
As a rule, the switchgear 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 free of dust as far as possible
• Dry and protected against humidity and vermin (e.g. insects, mice, rats)
• Heat to about 10 °C above outside temperature to prevent condensation
• Provide adequate ventilation in heated storage rooms
• 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
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 your regional SIEMENS representative.
