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 140 Celsius degrees and should not be lower than forty 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.
