Environmental conditions and attention

  • The altitude should not exceed 2000m and seismic intensity should not exceed 8 degrees.

    Ambient air temperature should not be higher than 50 Celsius degrees and should not be lower than forty-five below zero. The daily average differences between day and night temperatures should not be higher than 95% and monthly average should not be high than 90%.

  • The operating mechanism should not be installed in the places as below:

    The places with frequent violent vibration

    The places with great vapor、gas、chemical corrosive deposition、salt mist and dust.

    The place where it is easily inflammable and explosive.
