The unit requires a neutral connection (4 wire supply), and will not operate from a three wire
supply without the optional 200A-DSU delta-star converter.
It is essential that this unit is earthed.

1.2.3.1 Operation from a Single Phase Supply
If no three phase supply is available, it is possible to operate the 200A-3PH mk2 from a single
phase supply with reduced functionality. To connect the set to operate from a one phase
supply, connect L1, L2 and L3 to live, and N to neutral. When operating from a single phase
supply, all three outputs will be in phase.
