1 PLC的安装

    PLC适用于大多数工业现场，但它对使用场合、环境温度等还是有一定要求。控制PLC的工作环境，可以有效地提高它的工作效率和寿命。在安装PLC时，要避开下列场所：  

    （1）环境温度超过0 ~ 50℃的范围；  

    （2）相对湿度超过85%或者存在露水凝聚（由温度突变或其他因素所引起的）；  

    （3）太阳光直接照射；

    （4）有腐蚀和易燃的气体，例如*、硫化氢等；  

    （5）有打量铁屑及灰尘；  

    （6）频繁或连续的振动，振动频率为10 ~ 55Hz、幅度为0.5mm（峰-峰）；  

    （7）超过10g（重力加速度）的冲击。  

    小型可编程控制器外壳的4个角上，均有安装孔。有两种安装方法，一是用螺钉固定，不同的单元有不同的安装尺寸；另一种是DIN（德国共和标准）轨道固定。DIN轨道配套使用的安装夹板，左右各一对。在轨道上，先装好左右夹板，装上PLC，然后拧紧螺钉。为了使控制系统工作可*，通常把可编程控制器安装在有保护外壳的控制柜中，以防止灰尘、油污、水溅。为了保证可编程控制器在工作状态下其温度保持在规定环境温度范围内，安装机器应有足够的通风空间，基本单元和扩展单元之间要有30mm以上间隔。如果周围环境超过55C，要安装电风扇，强迫通风。  

    为了避免其他外围设备的电干扰，可编程控制器应尽可能远离高压电源线和高压设备，可编程控制器与高压设备和电源线之间应留出至少200mm的距离。  

    当可编程控制器垂直安装时，要严防导线头、铁屑等从通风窗掉入可编程控制器内部，造成印刷电路板短路，使其不能正常工作甚至*损坏。
