Connection diagrams for the control circuit power supply transformer (T1) as a function of the various customer power supply voltages.

The tension of the control circuit delivered by the transformer must be 230 volts, single-phase. The supply tension for your machine is normally of 400 volts between 2 phases, this tension can however be different. The following schemes show how to adjust the tension at the secondary of the transformer.

Measure the power supply voltage at the transformer primary with a voltmeter be- tween the transformer 0 and 400 volts terminals.

-If the voltage is equal to 400 volts, do not touch the transformer connection which must be as shown in the adjacent fi gure.

D0663

-If the voltage is > 400 volts (for example : 420 or 430 volts), connect the wires to the transformer as shown in the adjacent fi gure.

D0661

-If the voltage is signifi cantly < 400 volts (for example : 370 or 380 volts), connect the wires to the transformer as shown in the adjacent fi gure.
