Keep the transformer supplied with no-load for at least
12 hours, checking that there are no anomalies in any of
the transformer instruments.

irreversible damage to the transformer or to the
electrical installation.
• Before handling the installation, exactly follow the
instructions of Section 6.1 of this general instructions
