Remark:
CT wire (5m in length) specification: RJ45, standard LAN line (one end with 8P
modu-
lar plug, the other connected with transformer). But if the length is not enough,
customer can add cable, so the length can be increased to 15m max, the operation

During the actual operation, please pay attention to the installation of current
transformer as the diagram shows below:
As illustrated above, open the current transformer and you can see an arrow
labeled on it indicating the direction of current. Put the live wire among the under-
detection wires onto the current transformer. After latching the current
transformer, the installation has been finished
Notice:
The direction (from K to L) of the arrow on the current transformer is
corresponding to the direction of the current in live wire from Grid to Load. Sensor
needs to be placed in the power distribution cabinet.
