NOVAR 2600 Operating Manual
For networks without neutral wire, it is possible to connect all three voltages; then set 1Y3 connection
as at previous cases.
If one line-to-line voltage signal only is available it must be connected in different way : connect it to
the U1 and N terminals and set 1D3 connection type. The U2 and U3 inputs must be connected
together with the U1.
Be careful not to exceed maximum input voltage according the technical parameters when
the 1D3 connection type !!! Take into account that the network line-to-line voltage is
connected to the instrument line-to-neutral input !!!
