TEMP (1,2): ba�ery temperature sensor for lead
acid ba�ery.
CT-L1 (3,4): current transformer (CT1) for"zero
export to CT"mode clamps on L1 when
in three phase system.
CT-L2 (5,6): current transformer (CT2) for"zero
export to CT"mode clamps on L2 when
in three phase system.
CT-L3 (7,8): current transformer (CT3) for"zero export to CT"mode clamps on L3 when in
three phase system.
CN2:
G-start (1,2): dry contact signal for startup the diesel generator.
When the "GEN signal" is ac�ve, the open contact
(GS) will switch on (no voltage output).
G-valve (3,4): Dry contact output. When the inverter
is in off-grid mode and the "signal island mode" is
checked, the dry contact will switch on.
Grid_Ry (5,6): reserved.
RSD (7,8): When ba�ery is connected and the
inverter is in "ON" status, it will provide 12Vdc.
