For operation in an IT system (ungrounded), make simple adaptations by relocating the jumpers
(C
=OFF). However, this may result in impairment of radio interference suppression.

Take account of the insulation resistance of the device when operating on an insulation monitor (
Section 7 "Technical Data")

The device may also be operated in supply systems with a high-resistance grounded neutral point
(High-Resistance Grounding) (typical for the USA). Take account of the same conditions and
modifications here as those in an IT- system (see above).

Use on different supply networks or network types
The device may only be connected to supply networks which are explicitly stated in this section
( Section 2.4.2.1 "Power supply connection (L1, L2(/N), L3, PE)"). Operation on different network
types may be possible, but must be checked and explicitly approved by the manufacturer in
advance.
