The use of conditions
1. Ambient temperature
2. Altitude
3. Relative humidity2000m and below.Not more than 50% at a maximum temperature of +40° C, and greater relative humidity is allowed at lower temperatures:(e.g. 90% at +20P) should be taken into account due to A change in temperature may have an occasional effect on condensation.
4. The inclination between the equipment and the vertical plane shall not exceed 5.
5. The equipment should be installed in the place where there is no severe vibration and impact, and where the electrical
components are not corroded.
Note: if If the above conditions cannot be met, the user can negotiate with the company to solve the special requirements.
