4.Installation

• Installed CT before electrical circle layout, circle line must penetrate internal circle of Cts.
• Split CTs can install by anytime, with follow step:
1 .Disassembling clips K1 & K2.
2.Releasing 6 screws on the top of CT, and separating CT in Two parts
3.Surround CT on the line, clear two connecting interface, spread with anti-rust oil,then tight up those 6 screws, for keep best performance keep separated terminals well connected.
4. Clip on K1 &K2
5. Keep split CTs with origin.

Remarks: Circuit line must penetrate CT with grounding.
