4.  Normal conditions of use

1. Ambient air temperature is not higher than + 40 °C, no less than 5 °C;Shall not be higher than the average temperature within 24 h + 35 °C. Indoor installation, use the site the altitude of 2000 m.

2. Ambient air relative humidity at the highest gradient is not more than 5 .

3. Equipment should be installed in no violent vibration at to + 40 °C temperature does not exceed 50%, low temperature, the relative humidity of

the allowed have bigger (such as + 20 °C at 90%), should be considered due to the change in temperature may accidentally condensation effect.

4. Installation of equipment with vertical and impact, and place of the deficient

electric components from corrosion.

5. Users have special requirements to negotiate with factory to solve.
