Storage
During storage, a temperature range b10°C and
+35 °C is recommended in order to prevent premature
aging of components, particularly the electrolytic capacitors.
For longer storage periods, it is recommended that voltage
be applied to the device power supply for one or two days
every other year, in order to regenerate the electrolytic
capacitors. The same is valid before the device is finally
installed.
