Handling, transport and storage
Sepam in its original packaging
Transport:
Sepam can be shipped to any destination by all usual means of transport without
taking any additional precautions.
Handling:
Sepam can be handled without any particular care and can even withstand being
dropped by a person standing at floor-level.
Storage:
Sepam can be stored in its original packaging, in an appropriate location for several
years:
b Temperature between -25°C and +70°C (between -13°F and +158°F)
b Humidity y 90%.
Periodic, yearly checking of the environment and the packaging condition is
recommended.
Once Sepam has been unpacked, it should be energized as soon as possible.
Sepam installed in a cubicle
Transport:
Sepam can be transported by all usual means of transport in the customary
conditions used for cubicles. Storage conditions should be taken into consideration
for a long period of transport.
Handling:
Should the Sepam fall out of a cubicle, check its condition by visual inspection and
energizing.
Storage:
Keep the cubicle protection packing for as long as possible. Sepam, like all electronic
units, should not be stored in a damp environment for more than a month. Sepam
should be energized as quickly as possible. If this is not possible, the cubicle
reheating system should be activated.
Environment of the installed Sepam
Operation in a damp environment
The temperature/relative humidity factors must be compatible with the unit’s
environmental withstand characteristics.
If the use conditions are outside the normal zone, special arrangements should be
made before commissioning, such as air conditioning of the premises.
Operation in a polluted atmosphere
A contaminated industrial atmosphere (such as the presence of chlorine, hydrofluoric
acid, sulfur, solvents, etc.) can cause corrosion of the electronic components, in
which case environmental control arrangements should be made (such as
pressurized premises with filtered air, etc.) before commissioning.
The effect of corrosion on Sepam has been tested according to the
IEC 60068-2-60 standard. Sepam is certified level C under the following test
conditions:
b 2 Gas test: 21 days, 25°C (77°F), 75% relative humidity, 0.5 ppm H2S, 1 ppm SO2 b 4 Gas test: 21 days, 25°C (77°F), 75% relative humidity, 0.01 ppm H2S, 0.2 ppm
SO2 , 0.2 ppm NO2 , 0.01 ppm Cl2 6/3
