端子接线图

接线说明

互感器与仪表之间的连接线,采用每根线不小于1.5mm² 的铜双芯电缆连接。仪表电源进线经过高频磁环并且在磁环上绕一圈后与端子连接，高频磁环应靠近仪表端。

注意：穿过高频磁环的电源线只能为一根N线，一根L线不允许在配线时出现多根L线和N线同时穿过磁环。

Use 2-wire copper cable to connect the transformer and the relay, each copper wire should not be less than 1.5mm² . Connect power source wire to of the relay after a high-frequency magnetic core and with additional a roll wrapped, the high-frequency magnetic core should be close to the relay.

Attention: Only one N wire and one L wire can be placed to go through the high-frequency magnetic core, it is not allowed for multiple L wires and N wires to go through the core simultaneously
