9. Installation
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.
- 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.
- 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.
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.
