NINE ELEMENTS - SINGLE AND THREE PHASE

DIAGRAM 4.

CONVERSION TO SINGLE PHASE

When the heater is shipped for connection to a three-phase electrical service, it may be connected to a single-phase electrical service of the same voltage by:

1.Disconnect blue wires from terminal L2.

2.Connect all blue wires to terminal L1 (with black wires).

3.Disconnect all red wires from terminal L3.

4.Connect all red wires to terminal L-2 (with yellow wires).

5.Connect incoming power to terminals L1 and L2.

CONVERSION TO THREE PHASE

When heater is shipped for connection to a single-phase electrical service, it may be connected to a three-phase electrical service of the same voltage by:

1.Disconnect blue wires from terminal L1

2.Disconnect red wires from terminal L2.

3.Connect all blue wires to terminal L2 (with yellow wires).

4.Connect red wires to terminal L3.
