Mains transformer connection diagrams according
to the customer's various mains voltages
(machines equiped with a transformer only).
400 Volts supply
Measure the mains voltage at the
primary with a voltmeter between 0 and
400 volts of the transformer.
- If the voltage is equal to 400 volts, do
not touch the transformer connection
which should be as indicated in the
margin.
- If the voltage is > à 400 volts (example:
420/430 volts), connect the threads
to the transformer as indicated in the
margin.
Note : the latter solution is advised
even it the voltage is normally equal
to 400 Volts, but may be subject
to time variations ; your machine
electrical equipment will not be
overfed.
- If the voltage is far < 400 volts
(example: 370/380 volts), connect the
threads to the transformer as indicated
in the margin.
