4.1.3
DN DN750…1850
The DN750…1850 is connected as
TN-S Network
. Three phases (L1, L2, L3) and the
protective conductor (PE) are required. Neutral and protective conductor laid separately. A
terminal connector for the neutral conductor is available but connection is not necessary.
Voltage, current and frequency ranges, according to 10.2!

4.2 Prefuse
For maximal and minimal prefuse see electric circuit diagram.
4.2.1 Operator Protection
If a RCCB or ELCB is used it needs to be a
universal current sensitive RCCBs B
type
, suitable for protecting frequency inverters.
In case of false triggering of the RCCB, we recommend installation of a leakage compensation
(See chapter troubleshooting).
4.3 Coil module connector HAN 3/HAN 10 B
The coil module is connected with a HAN 3 (DN150) or HAN 10 B (DN750-1850) to the power
module and latched.
