the NE module must be connected
through an isolating transformer.
Symmetrical 3–conductor or 4–conductor three–phase line supply without a
directly grounded point, the loads are, e.g. connected to grounding electrodes.

Note
When using isolating transformers upstream from I/R and UI modules
(module width
 100 mm), an overvoltage limiting module should be used,
Order No.: 6SN1111–0AB0V–0AA0; refer to Section 7
UI modules 5 kW Order No.: 6SN1146–2AB00–0BA1, a voltage limiting circuit
is included.
