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

7.2 Mechanical and climatic conditions
The modules of the

Ç

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.

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.
