WARNING
If the device is operated on a network in which a phase is grounded instead of the
neutral, the plant operator must ensure that fans (terminals X19-1, X19-2) and the main
contactor circuit (terminals X9-4, X9-5) are fed from this phase and the neutral.
If it is not possible to ensure this, the fans and main contactor circuit must be fed from an
isolating transformer.
Moreover, the feed to terminals X19-1, X19-2, X9-4, X9-5 must be implemented via an
isolating transformer if:
● The connection between the protective ground and electronic ground is interrupted
(see Chapter 3.3.3 Terminals on the CUR Module).
● The rectifier/regenerating unit is operated in an ungrounded network.
