7 General conditions

This chapter describes the general conditions for error-free running of the :$*2Ç,￿2Ç6<67(0

7.1Transporting and storing conditions

The following declarations concern modules which are transported and stored in the original package.

Condition

Free fall

Temperature

Relative humidity

allowed values

≤1m

-40° to +70° C

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 SO2 must be below 25 ppm with a relative humidity of < 75%. The concentration of H2S must be below 10 ppm with the same humidity.

The mechanical conditions are given as sinusoidal oscillations.

Frequency range (Hz)

10 ≤ f < 57

57 ≤ f ≤ 150

continuous

0.0375 mm amplitude

0.5 g constant acceleration

sometimes

0.075mm amplitude

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.
