路灯接地
内置驱动的路灯接地,接地能固定到PCB板然后到外壳这种接地吗?同问有款I类灯具接地直接是接到LED PCB板上然后连接外壳的这样做是否合格? 接地应该先连到灯具金属外壳,再连接到驱动。不能先连到PCB,再外壳。
It is allowed to earth built-in control gear by means of fixing the control gear to earthed metal
parts of the luminaire. Connection to protective earthing of the luminaire via the built-in control
gear is not allowed. 学习下,谢谢 接地一定要加上菊花垫片吗
