Commutating reactors: Selection of the power system commutating reactors with u
on Table 3.4 and Catalog DA93.1.
Fuses: Refer to Table 3.3. for fuse order numbers.
Output reactors in the DC circuit are not permitted (even with the parallel connection of power sections or in
12-pulse mode), because the DC link voltage is measured at the unit output terminals.

(19343-T7A/250V Messrs. Wickmann-Werke GmbH or 0034.5243 FST Messrs. Schurter)
Where the unit is operated in conjunction with a power system, one phase of which is
earthed and not the starpoint, the plant management must ensure that power supply to
the fan circuit (terminals X19-1, X19-2) and to the main contactor circuit (terminal X9-4,
X9-5) is taken from this phase and the starpoint.
Where this cannot be ensured, the power supply to the fan circuit and to the main
contactor circuit must be taken via an isolating transformer.
In addition, the power supply to terminals X19-1, X19-2, X9-4, X9-5 must be taken via an
isolating transformer, when:
• the connection to ground - electronic ground is interrupted (refer to Chapter 3.3.3
• the power supply unit is operated in conjunction with a non-grounded power supply
