the busbar, then tighten the bolts holding the busbars
in place to 20 Nm.

busbars and screw the assembly to the body of the
starter (see note).

cable ties.
NOTE
If moving the input busbars, the current transformers (CTs) must also be reconfigured.
1. Label the CTs L1, L2 and L3 (L1 is leftmost when looking from the front of the starter). Remove the
cable ties and unscrew the CTs from the bracket.
2. Move the CT bracket to the top of the starter. Position the CTs for the correct phases, then screw the
CTs to the bracket. For models D3-0360-N ~ D3-0930-N, the CTs must be placed on an angle (the left
hand legs of each CT will be on the top row of holes and the right hand legs will be on the bottom
tabs).
