1. Stop the engine and turn the main circuit breaker off.
2. Turn the voltage selector switch to the 208/240 position.
3. Open the lug door and connect the wires from the load(s) as shown.

When connecting multiple 120V loads:
Use L1 as "hot" for first load.
Use L3 as "hot" for second load.
Use L2 as "hot" for third load.
Balance the load
Fine-tune the voltage so that
both the 3-phase load and
the single-phase loads
operate properly.
