    本文由新语丝北京翻译公司资深译员进行翻译整理

    (一)安装要求

    整流器的安装应平稳、牢靠,其上不得放置其他物品。

    安装位置需保持良好的通风条件或放置于有冷气装置的场所。

    整流器后面板出风口500mm范围内和侧面200mm范围内不应有妨碍空气流通的物品。(见图1)

    多台整流器同时使用时,需保持良好的排风和散热设备。

    (二)环境要求

    使用场所:不得放置于屋外或可能受潮的地方,尽量避免阳光直接照射。

    周围温度:工作温度由-10℃~40℃之间。

    相对湿度:保持干燥通风,尽量不要有水分凝结现象,相对湿度保持在85%以下。

    落 尘 量:请将整流器放置于灰尘较少的地方。

    (三)接线方法

    供电线的接法

    供电电压为220VAC±10%、50Hz。

    将电源电缆与整流器和网电正确连接(见图2),L接火线、N接零线、G接大地。

    电缆规格:2.5KW以下选用截面积为2.5mm2导线;2.5KW以上选用截面积为4mm2导线。

    确保连接处牢固、绝缘。

    检查接地线必须连接可靠,避免因感应电而发生危险。

    负载线的接法

    如图2所示,阳极->“+”铜排,阴极->“-”铜排。注意“+”、“-”极性不要接反。

    电流密度:按3~5A/mm2选取,如果电缆较长,应适当增加电缆截面积。

    电缆的长度要合适,避免线缆与整流器连接处受力。

    所有电缆接头线鼻子一定要紧固牢靠。

操作手册翻译

    (I) Requirements on installation

    1.The rectifier must be installed stably and securely, no other things placed on its top.

    2.The position for installing the rectifier must be well-ventilated or placed at places with refrigerating unit.

    3.Within 500mm away from the air outlet and 200mm from the sides of rear panel, there must be free of any things disturbing the air ventilation.(see figure 1 for details)

    4.If several rectifiers are used as the same time, there rectifiers must be kept in well-ventilated and well-radiated of heat conditions.

    (II) Ambient conditions

    1.Applications: this rectifier must not be placed at outdoor or places to be affected with damp, not to be shined directly.

    2.Ambient temperature: the range of working temperature is -10℃~40℃.

    3.Relative humidity: the rectifier must be placed at well-ventilated conditions to avoid condensing, with the relative humidity below 85%.

    4.Dust protection: the rectifier should be protected against dust depositing.

    (III) Wiring methods

    1.Wiring of power feeder

    Supply voltage is 220VAC±10%,50Hz.

    The power cable and rectifier must be properly connected with grid (see figure 2 for details), L is connected to live line, N is connected to zero line, G is connected to earth.

    Size of wire: the wire with the section of 2.5mm2 should be specified for 2.5KW and below, and the wire with the section of 4mm2 should be specified for 2.5KW and above.

    Ensure the connections fixed securely and insulated.

    Check whether the grounding conductor fixed securely or not to avoid the electric shock caused by induction.

    2.Wiring of load lines

    (1)Shown as figure 2, positive pole->“+”, copper strip, negative pole->“-” copper strip. Caution; the “+” and  “-”poles must not be connected in reverse order.

    (2)Current density: specified within 3~5A/mm2, if the wire is too long, the section of wire should be increased accordingly.

    (3)The length of cable must be properly specified to avoid tensing at the connections of wire and rectifier.

    (4)All wiring clips must be fixed securely.
