4. Installation Instructions
4.1 Integrated CT should be installed before laying cables, and cables go through CT.
4.2 Open zero-sequence CT could be installed at any time and the details as follows:
1)remover connecting presser of K1and K2 on CT.
2)After loosening and removal of inner hexagon bolts on the top of CT, it comes into two parts. 
3)Fix the CT on the cable, clean the two touching surface, coat anti-rust oil, align the two parts and fasten inner hexagon bolts.
4)Fix the connection sheets at K1 and K2 position.
