Application: 1) TQA1 series crane console (for short: console) is applied for main circuit and control circuit in AC 50HZ, rated voltage 380V and DC rated voltage 220V, and can be worked with crane protective cabinet or control screen, starting, timing, commuting and braking motors 2) Setting term: a) Altitude does not exceed 2,000m the ambient temperature between +40 and -5°C. Average temperature less than +35°C during 24 hours b) The air is clean, the relative humidity does not surpass 50% under +40 maximum temperatures, in compares under the low temperature the relative humidity may enhance (for example when 20 is 90%), and the permission but possibly accidentally produces as a result of the temperature change in the product surface mildly congeals the dew c) The power supply electrical network quality is qualified; the coil in voltage undulation scope does not surpass the rated voltage value 10% e) The vertical installment, the gradient does not surpass 5, must install reliably, should not produce vertically in the main engine work beats with the level migration
