7 General conditions
This chapter describes the general conditions for error-free running of the
:$*2Ç,2Ç6<67(0
7.1 Transporting and storing conditions
The following declarations concern modules which are transported and stored in the
original package.
Condition allowed values
Free fall
≤ 1m
Temperature -40° to +70° C
Relative humidity 5 to 95% (without condensation)
7.2 Mechanical and climatic conditions
The modules of the :$*2Ç,2Ç6<67(0 are not allowed to be operated without
taking suitable actions
- in places with strong conditions e.g. very dusty rooms or corroding atmosphere
- in place with high concentrations of ionisation
The temperature should be in a range between 0° C and +55° C. The relative humidity
should be in a range of 5 to 95% (without condensation).
The modules should be placed horizontal for better heat dissipation.
The concentration of SO
2
must be below 25 ppm with a relative humidity of < 75%. The
concentration of H
2
S must be below 10 ppm with the same humidity.
The mechanical conditions are given as sinusoidal oscillations.
Frequency range (Hz) continuous sometimes
10 ≤ f < 57
0.0375 mm amplitude 0.075mm amplitude
57 ≤ f ≤ 150
0.5 g constant acceleration 1 g constant acceleration
For stronger impulses and oscillations, the acceleration and the amplitude should be
reduced by suitable actions. The following table shows the type of test for the
mechanical conditions.
