STORAGE
Devices must be stored in a dry and clean environment. A temperature range of
-25°C to +70°C (-13°F to +158°F) must be maintained during storage (see
chapter entitled “Technical Data”). The relative humidity must be controlled so
that neither condensation nor ice formation will result.
If the units are stored without being connected to auxiliary voltage, then the
electrolytic capacitors in the power supply area need to be recharged every
4 years. Recharge the capacitors by connecting auxiliary voltage to the P631 for
approximately 10 minutes.
If the units are stored during a longer time, the battery of the power supply
module is used for the continuous buffering of the event data in the working
memory of the processor module. Therefore the battery is permanently required
and discharges rapidly. In order to avoid this continuous discharge, it is
recommended to remove the power supply module from the mounting rack
during long storage periods. The contents of the event memory should be
previously read out and stored separately!
