Storage

During storage, a temperature range between +50°F (10°C)
and +95°F (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.
