6.2 Storing a Device
Only store devices on which you have carried out an incoming inspection. This action ensures that the
²
warranty remains valid.
SIPROTEC devices must be stored in rooms, which are clean and dry. Devices or associated replacement
²
modules must be stored at a temperature range of -40 °C to +85 °C.
The relative humidity must be at a level where condensed water and ice are prevented from forming.
²
Siemens recommends that you observe a restricted storage temperature range of +10°C to +35 °C, in
²
order to prevent the electrolytic capacitors used in the power supply from aging prematurely.
If the device has been in storage for more than 2 years, connect it to an auxiliary voltage for 1 to 2 days.
²
This will cause the electrolytic capacitors to form on the printed circuit board assemblies again.
