2.2.2. Transformer
If the power supplied by the interface cable does not meet the required 220V AC the transformer must be
used.
The incoming power must be connected to the Primary Terminal Block. Use the contacts corresponding
to the supplied power (346V AC to 440V AC, see drawing below).
The outgoing power is always connected to the 220VAC terminals of the Secondary Terminal Block.
