Recommended order of installation for cables: 1. DC Power

2. Bypass Neutral

3. Bypass Input Power (Phases A-B-C)

4. Rectifier Input Power (Phases A-B-C)

5. Output Power (Phases A-B-C)

6. Output Neutral

7. Ground

The cables must be routed around the fault braces. This is to prevent the cables from coming in contact with

other busbars.
