在变频器实际应用中，由于国内客户除少数有专用机房外，大多为了降低成本，将变频器直接安装于工业现场。工作现场一般是灰尘大、温度高，在南方还有湿度大的问题。对于线缆行业还有金属粉尘，在陶瓷、印染等行业还有腐蚀性气体和粉尘，在煤矿等场合，还有防爆的要求等等。因此必须根据现场情况做出相应的对策。
2.1变频器的安装设计基本要求
(1)变频器应该安装在控制柜内部。
(2)变频器最好安装在控制柜内的中部;变频器要垂直安装，正上方和正下方要避免安装可能阻挡排风、进风的大元件。
(3)变频器上、下部边缘距离控制柜顶部、底部、或者隔板、或者必须安装的大元件等的最小间距，应该大于300mm。如图1中的H1，H2间距所示。
(4)如果特殊用户在使用中需要取掉键盘，则变频器面板的键盘孔，一定要用胶带严格密封或者采用假面板替换，防止粉尘大量进入变频器内部。
(5)对变频器要进行定期维护，及时清理内部的粉尘等。
(6)其它的基本安装、使用要求必须遵守用户手册上的有关说明;如有疑问请及时联系相应厂家技术支持人员。
