机组总电源进线为五色电缆,接入机组电器柜的相应接线端子排上;在连接机组总电源进线时,需要注意五色电缆中线直径较细的芯线接三相电源中线,黄绿线接地,其余三根线接电源。

在机组接通主电源前,应对三相交流供电进行检查,以确保所供电压波动范围不超过设备表明电压及频率的10%,对于高负荷场合能够引起电压的波动,此项检查尤为重要;机组必须接地,且设置带熔断器的空气开关以保证设备在检查和服务时与电源绝缘。

熔断器的熔断功率必须与所安装机组的型号及类型相一致。熔断器应该安装在容易触及的机组控制板上;电缆尺寸及熔断功率,供电电缆及主电熔器对于所安装的机组来说必须有对应正确的尺寸及熔断功率,细节参见附后的电气资料;机组的电源进线上需要增加火警断电保护以便及时发现问题、减少不必要的麻烦。
