Line chokes
Project Planning
For connecting
several single-
phase inverters
to one three-
phase line choke
Prerequisites for connecting several single-phase inverters to one three-phase line
choke are:
•
The supply system contactor must be designed for the total current.
•
The fuse must correspond to the rated current value of the line choke.
•
Connect MOVITRAC
®
07 frequency inverters to the line chokes symmetrically.
Example: Two sin-
gle-phase inverters
on one single-
phase line choke
Two MOVITRAC
®
07MC07A008-2B1 units (0.75 kW) are connected to one line choke
ND 020-151. The rated current of the inverters is 9.9 A.
Make sure the line cross section corresponds to the selected fuse. In addition, you must
configure the neutral conductor in accordance with the total current.
