14.1.5 Storage
If the device is not to be used immediately, it can be stored.
Please observe the following:
SIMEAS R-PMU devices must be stored in dry and clean rooms. The device and its replacement
modules must be stored within the temperature range of -25 °C to +70 °C (see Chapter 16).
To avoid premature aging of the electrolyte capacitors used in the power supply, a limited
temperature range of +10 °C to +35 °C is recommended for storage.
The relative humidity must not lead to condensation or ice formation.
With battery-buffered devices, it must be ensured that the battery is not damaged by total
discharge due to long storage times.
After extended storage, the power supply of the device should be energized, approximately
every two years, for one or two days to regenerate the electrolytic capacitors in the power supply
unit. This should also be done before the device is put into service.
The device must be in the final operating room for a minimum of two hours before the power
source is first applied after storage. This allows the device to attain temperature equilibrium, and
dampness and condensation are avoided.
CAUTION
Caution with defective devices with transport damage.
Nonobservance of the safety instructions means that moderately severe or slight inju-
ries can occur.
• Devices that have been damaged during transport must not, under any circumstances, be
connected and put into service.
Note
Please bear in mind that such measures apply both for complete devices and individual modules.
