Grid Line
The power line called "GRID" (terminal block "QG-M1", terminals "L1.1", "N1.1") is the line that must be connected
in parallel to the electrical line connecting the three-phase energy meter to the general panel low voltage of the
utility (for the electrical connection follow the instructions given in the wiring diagram supplied with the product).
The "GRID" line supplies or withdraws energy only when the national grid is active (V grid = 230 Vac).
3.3.6.3
EPS Line (AC Back up)
The power line called "EPS" (terminal block "QG-M1", terminals "L2.2", "N2.2") is the ac line of back-up that must be
connected only in the presence of the switchboard, external to accumulation system, between the lines “EPS”
and
“GRID” (for the electrical connection follow the instructions given in the
wiring diagram supplied with the product).
Without the switchboard the connection of the EPS line can not be realized
.
The "EPS" line does not require any setting or activation; it supplies energy only when the national grid is not active
(V grid = 0 Vac).
